Abstract

Provided is a jig which assists in the adhesion of a thin-film sheet to an adhesion target surface (skin etc.), and which can easily adhere the thin-film sheet to the adhesion target surface. The jig includes: a base part having a first surface; and a porous hydrophilic film that is adhered to the first surface and has fine pores with a predetermined porosity, wherein the porosity is 35% to 55% inclusive. The hardness of the base part is preferably 4-20 inclusive. In addition, it is preferable that the base part and the hydrophilic film have transparency.

First claim

The invention claimed is:

1. A jig that assists in attaching a thin sheet to a target surface, the jig comprising:
a substrate having a first surface;
a porous hydrophilic film which is attached to the first surface of the substrate,
wherein the porous hydrophilic film has an Asker C hardness of 4 degrees or more and 20 degrees or less; and
a base that is attached to a surface of the substrate opposite to the first surface, wherein the base has a frame-shaped outer shape.

2. A jig that assists in attaching a thin sheet to a target surface, the jig comprising:
a substrate having a first surface;
a porous hydrophilic film which is attached to the first surface of the substrate, wherein the porous hydrophilic film has pores with a porosity of 35% or more and 55% or less; and
a base that is attached to a surface of the substrate opposite to the first surface, wherein the base has a frame-shaped outer shape.

3. A jig that assists in attaching a thin sheet to a target surface, the jig comprising:
a substrate having a first surface, wherein the substrate has an Asker C hardness of 4 degrees or more and 20 degrees or less;
a porous hydrophilic film which is attached to the first surface of the substrate; and
a base that is attached to a surface of the substrate opposite to the first surface, wherein the base has a frame-shaped outer shape.

4. The jig according to claim 1 , wherein the porous hydrophilic film has transparency.

5. A jig that assists in attaching a thin sheet to a target surface, the jig comprising:
a substrate having a first surface;
a porous hydrophilic film which is attached to the first surface of the substrate; and
a base that is attached to a surface of the substrate opposite to the first surface,
wherein the base has a frame-shaped outer shape,
and wherein the base has an Asker C hardness of 5 degrees or more.

6. The jig according to claim 1 , wherein the substrate has transparency.

7. The jig according to claim 1 , wherein the substrate includes a convex R curved surface.

8. The jig according to claim 1 , wherein the substrate entirely has a convex R curved surface.

9. The jig according to claim 7 , wherein the convex R curved surface has a radius of curvature R of 30 mm or more and 150 mm or less.

10. The jig according to claim 7 , wherein the convex R curved surface has a radius of curvature R of 40 mm or more and 90 mm or less.

11. The jig according to claim 1 , wherein the base has a through-hole in a central portion.
