Abstract

A conductive resin body includes a plurality of conductive fibers which are made of at least one type of carbon fibers, high-strength fibers, and glass fibers, and which are metal plated. A metal member is electrically connected to the plurality of conductive fibers. The conductive resin body also includes resin in which a part of the metal member is buried and with which the plurality of conductive fibers are impregnated. A rest of the metal member is exposed from the resin.

First claim

What is claimed is:

1. A conductive resin body comprising:
a plurality of conductive fibers which comprise at least one type of carbon fibers, high-strength fibers, and glass fibers, and which are metal plated;
a metal member which is electrically connected to the plurality of conductive fibers; and
resin in which a first part of the metal member is buried and with which the plurality of conductive fibers are impregnated, wherein a second part of the metal member is exposed from the resin,
wherein a height of the metal member is substantially constant when viewed along a cross-section of the conductive resin body.

2. The conductive resin body according to claim 1 ,
wherein the plurality of conductive fibers have a structure of a stacked body in which two or more layers are stacked, and
wherein the metal member is a planar thin metal member positioned between two adjacent layers of the two or more layers.

3. The conductive resin body according to claim 2 ,
wherein the metal member includes a plurality of openings.

4. The conductive resin body according to claim 1 ,
wherein the plurality of conductive fibers are arranged in a plane, and
wherein the metal member includes a frame member positioned along an outer peripheral side of the plane in which the plurality of conductive fibers are arranged.

5. An earth of a vehicle comprising:
the conductive resin body according to claim 1 , which is used as a body for a vehicle,
wherein a portion of the metal member of the conductive resin body, which is exposed from the resin, is electrically connected to a negative terminal of a in-vehicle device and a vehicle battery.

6. The conductive resin body according to claim 1 , wherein the metal member is not stacked with additional metal members.

7. The conductive resin body according to claim 1 , wherein the metal member is a unitary body.

8. A conductive resin body comprising:
a plurality of conductive fibers which comprise at least one type of carbon fibers, high-strength fibers, and glass fibers, and which are metal plated;
a metal member which is electrically connected to the plurality of conductive fibers; and
resin in which a first part of the metal member is buried and with which the plurality of conductive fibers are impregnated, wherein a second part of the metal member is exposed from the resin,
a conductive metal pin,
wherein the plurality of conductive fibers are arranged in a plane,
wherein the metal member is a planar thin metal member that is stacked on the plurality of conductive fibers arranged in the plane, and
wherein the metal pin extends in a direction intersecting with the plane, and electrically connects the plurality of conductive fibers and the metal member.

9. A method for manufacturing a conductive resin body comprising:
metal plating a plurality of fibers which are made of at least one type of carbon fiber, high-strength fiber, and glass fiber to produce a plurality of conductive fibers;
assembling and electrically connecting a metal member to the plurality of conductive fibers, wherein a height of the metal member is substantially constant when viewed along a cross-section of the conductive resin body; and
molding an assembly with resin such that a first part of the metal member is buried in the resin and a second part of the metal member is exposed from the resin.

10. The method for manufacturing a conductive resin body according to claim 9 , further comprising:
molding the plurality of conductive fibers with the resin and forming an intermediate member which is metal plated before the assembling and electrically connecting,
wherein, in the assembling and electrically connecting, the metal member is electrically connected to the plurality of conductive fibers which the intermediate member includes.
