Provided are a conductive adhesive and an anisotropic conductive film capable of suppressing deterioration by halogen at an adhesion portion, and using an epoxy (meth) acrylate resin, and further provided is an electronic device using such a conductive adhesive and an anisotropic conductive film. In a conductive adhesive and an anisotropic conductive film comprising conductive fillers and a binder resin, an epoxy (meth)acrylate resin contained in the binder resin is formed by adding a (meth) acrylic acid to an epoxy compound having the sum of total chlorine atom concentration and total bromine atom concentration of 300 mass ppm or less, and preferably 50 mass ppm or less, and the conductive fillers are dispersed in the binder resin containing the epoxy (meth)acrylate resin. The epoxy (meth) acrylate resin can be obtained by using raw material compound (substrate) having a carbon-carbon double bond, epoxidizing the carbon-carbon double bond preferably using hydrogen peroxide as an oxidant, and further adding a (meth)acrylic acid thereto.

[Problem] The present invention addresses the problem of providing: a polyarylene sulfide resin composition which contains nickel microparticles having a smaller average particle diameter; and a method for producing the polyarylene sulfide resin composition, which is simple and widely applicable. The present invention also addresses the problem of providing a production method which comprises converting a cyclic polyarylene sulfide to a polyarylene sulfide, and which enables the polyarylene sulfide to be produced steadily, at a low temperature and within a short time of period. [Solution] A polyarylene sulfide resin composition containing nickel microparticles having an average particle diameter of 0.5 to 20 nm is produced by heating a cyclic polyarylene sulfide in the presence of at least one component selected from components (i), (ii) and (iii).
