Abstract

A method for producing an electrical wiring member includes press-molding a composition containing a resin material and metal particles with an insulating layer, each of which is constituted by a metal particle and a surface insulating layer covering the metal particle and containing a glass material as a main material, thereby obtaining a powder-compacted layer and irradiating the powder-compacted layer with an energy beam, thereby causing the irradiated regions to exhibit electrical conductivity.

First claim

What is claimed is:

1. An electrical wiring member production method, comprising:
preparing a composition that contains a resin material and metal particles with an insulating layer, the metal particles with the insulating layer being formed by:
preparing the metal particles having electrical conductivity; and
placing the insulating layer on an outer surface of each of the metal particles, the insulating layer being made of a glass material as a main material;

molding the composition so as to form a molded body; and
irradiating the molded body with an energy beam so that the irradiated region becomes an electrical wiring.

2. The electrical wiring member production method according to claim 1 ,
wherein the metal particles with the insulating layer are produced by fixing the glass material on the outer surface of each of the metal particles.

3. The electrical wiring member production method according to claim 1 ,
wherein the molded body is obtained by pressurizing a mixture of the metal particles with the insulating layer and the resin material in the molding.

4. The electrical wiring member production method according to claim 1 ,
wherein the metal particles are produced by one of a water atomization method or a spinning water atomization method.

5. The electrical wiring member production method according to claim 1 , wherein the resin material contains an epoxy-based resin.

6. The electrical wiring member production method according to claim 1 , further comprising:
heating the molded body before the irradiating.

7. The electrical wiring member production method according to claim 6 , wherein the heating is performed both during and after the molding.

8. The electrical wiring member production method according to claim 6 , wherein a heating temperature of the heating is 130° C. or higher and 180° C. or lower.

9. The electrical wiring member production method according to claim 6 , wherein a heating time of the heating is 5 minutes or more and 2 hours or less.
