The housing as claimed in claim 1 , wherein the housing further includes a plurality of connecting members and gaps, the housing is spaced by the opening to form at least one main base, the connecting members are respectively positioned in gaps between each two adjacent metal sheets, and between each main base and one metal sheet adjacent to the main base, such that the metal sheets and the main base are bonded together through the connecting members, each connecting member has a width of about 0.02 mm to about 0.7 mm along a direction from an adjacent connecting member located at one side of metal sheet to another adjacent connecting member located at an opposite side of the metal sheet.

3 . The housing as claimed in claim 2 , wherein each metal sheet has a width of about 0.15 mm to about 1.0 mm along a direction from an adjacent connecting member located at one side of metal sheet to another adjacent connecting member located at an opposite side of the metal sheet.

4 . The housing as claimed in claim 2 , wherein the substrate includes a footwall, two opposite sidewalls, the sidewalls are respectively located at two opposite sides of the footwall; the housing further includes a non-conductive member formed on a bottom of the opening, the non-conductive member covers at least a portion of the footwall and the sidewalls, the metal sheets, the main base, the reinforcing member and the connecting member are all bonded with the non-conductive member.

5 . The housing as claimed in claim 4 , wherein each sidewall has an accommodating groove, the footwall also has an accommodating groove, the non-conductive member is positioned in the accommodating grooves of the sidewalls and the footwall.

6 . The housing as claimed in claim 5 , wherein the footwall corresponding to the accommodating groove has a thickness of about 0.3 mm to about 0.5 mm, each sidewall corresponding to the accommodating groove has a thickness of about 0.2 mm to about 0.4 mm.

7 . The housing as claimed in claim 6 , wherein the main base and each metal sheet all have a dielectric layer, the dielectric layer has a thickness of about 8 μm to about 25 μm.

8 . The housing as claimed in claim 1 , wherein two opposite sides of the footwall both have a plurality of grooves, each sidewall also has grooves; the substrate further includes two pairs of two opposite fastening structures, one end of each fastening structure is located at the sidewall, the opposite end of each fastening structure is located at the footwall along a direction extending from the sidewall to the footwall, each end of the fastening structure located at the sidewall and the footwall has two through-holes, the grooves are connected with the corresponding through-holes.

9 . The housing as claimed in claim 8 , wherein each metal sheet includes an end wall, and two sidewalls, the sidewalls are respectively connected with two opposite ends of the end wall, two opposite ends of the end wall both have a cavity, each sidewall includes a bending member and an extending member, each bending member has a cavity, one end of the reinforcing member successively passes through one groove formed on the footwall or sidewalls, one through-hole connected with the groove, a cavity adjacent to the through-hole, another through-hole facing the through-hole, and then the end of the reinforcing member is bended to form a hook, opposite end of the reinforcing member also successively passes through another groove formed on the footwall or sidewalls, another through-hole connected with the groove, the cavity adjacent to the through-hole, a through-hole facing the another through-hole, and then the opposite end of the reinforcing member is partly bended to form another hook.

10 . The housing as claimed in claim 9 , wherein the end wall and each bending member both have a width of about 0.8 mm to about 1.0 mm perpendicular to a direction from a connecting member located at one side of a metal sheet to an adjacent connecting member located at the opposite side of the metal sheet, each extending member has a width of about 0.3 mm to about 0.5 mm perpendicular to a direction from a connecting member located at one side of a metal sheet to an adjacent connecting member located at the opposite side of the metal sheet, the width of the extending members is equal to the thickness of the sidewall.

11 . The housing as claimed in claim 1 , wherein the reinforcing members are made of a metal, each reinforcing member has an isolative layer having a thickness of about 10 μm to about 30 μm.

12 . The housing as claimed in claim 1 , wherein the reinforcing members are made of a glass fiber, each reinforcing member has a protective layer having a thickness of about 0.02 mm to about 0.5 mm.

13 . A method of making a housing comprising:
providing a substrate; cutting the substrate to form an opening, the substrate being spaced by the opening to form at least one main base; a plurality of metal sheets and a plurality of reinforcing members are provided; and placing the metal sheets, the reinforcing members and the main base into a mold, the metal sheets being positioned in the opening, adjusting width of each gap between adjacent metal sheets, and between the main base and one metal sheet adjacent to the main base, locating the reinforcing members in the metal sheets and the main base, liquid resin being filled into the gaps and covering the reinforcing members to bond the metal sheets, the main base and the reinforcing members together, forming the housing.

14 . The method as claimed in claim 13 , wherein the method further includes a step of thinning sections of a portion of the footwall and the sidewalls to form an accommodating groove on the footwall and a groove on each sidewall before cutting the substrate, the non-conductive member is positioned in the accommodating grooves of the footwall and the sidewalls.

15 . An electronic device comprising:
