Abstract: A conductive composition includes conductive particles, a thermoplastic resin, and a solvent, wherein a glass transition temperature of the thermoplastic resin is 140 to 200 degrees C.

Abstract: A conductive paste that can reduce an increase in electrical resistance caused by stretching of a wiring when the wiring of an electrical circuit and/or an electronic circuit is formed on a surface of a stretchable and/or bendable base material. The stretchable conductive paste includes (A) surface-treated silver particles and (B) a thermoplastic resin. The (A) surface-treated silver particles include a surface-treated layer.

Abstract: To provide an epoxy resin composition which can form a cured material having low dielectric constant and low dielectric loss tangent in a radio frequency region, and a film obtained by using the epoxy resin composition. An epoxy resin composition comprising: (A) at least one epoxy resin selected from the group consisting of a novolac epoxy resin having a phenolic skeleton and a biphenyl skeleton, and a bifunctional linear epoxy resin having a weight average molecular weight of 10,000 to 200,000 and having a hydroxyl group; and (B) a modified phenolic novolac having a phenolic hydroxyl group, at least part of which is esterified with a fatty acid.
