Abstract
A wiring body includes an adhesive layer and a conductor pattern bonded to the adhesive layer. A surface roughness of an adhesive surface in the conductor pattern bonded to the adhesive layer is rougher than a surface roughness of another surface, which is a surface of the conductor pattern except for the adhesive surface in the conductor pattern.
Claims16
A wiring body comprising:
- an insulating member;
- and
- a conductor pattern bonded to the insulating member and comprising conductive particles and binder resin, wherein
- the conductor pattern is bonded to the insulating member after the conductor pattern is cured,
- the conductor pattern includes:
- an adhesive surface bonded to the insulating member;
- and
- another surface that is a surface of the conductor pattern except for the adhesive surface, and
- a surface roughness of the adhesive surface is rougher than a surface roughness of the another surface, wherein
- a part of the conductive particles protrudes from the binder resin on an adhesive surface of the conductor pattern bonded to the insulating member, and
- a boundary, formed after the insulating member is disposed on the cured conductor pattern, between the insulating member and the conductor pattern has a concave-convex shape corresponding to a concave-convex shape based on the surface roughness of the adhesive surface.

A method for producing a wiring body, comprising:
- a first process of filling a recessed portion of intaglio with an electrically conductive material comprising conductive particles and binder resin;
- a second process of forming a concave-convex shape on an upper surface of the electrically conductive material by performing at least one of drying, heating, and irradiating with an energy ray the electrically conductive material filling the intaglio, wherein the concave-convex shape is formed by the conductive particles that protrude from the binder resin;
- a third process of disposing an insulating material on the concavo-convex shape after the second process so that the insulating material is introduced into a concave of the concavo-convex shape;
- and
- a fourth process of releasing at least the insulating material and the electrically conductive material from the intaglio.
