    摘要: The present invention provides a conductive paste that has excellent printability, that can provide a printed electrode with a smooth surface, and that is excellent in storage stability. The present invention relates to a conductive paste used for formation of an electrode of a multilayer ceramic capacitor, the conductive paste including: a polyvinyl acetal resin that contains a carboxylic acid-modified polyvinyl acetal resin; an organic solvent; and a conductive powder, the polyvinyl acetal resin having an average degree of polymerization of 200 to 800, an carboxyl group content of 0.05 to 1 mol%, a hydroxy group content of 16 to 24 mol%, an acetyl group content of 0.1 to 3 mol%, and an acetoacetal group content of not more than 25 mol%, the carboxylic acid-modified polyvinyl acetal resin having at least one of a structural unit that has a carboxyl group represented by the formula (1-1) and a structural unit that has a carboxyl group represented by the formula (1-2): in the formula (1-1), R 1 and R 2 each independently representing a C0-C10 alkylene group, X 1 and X 2 each independently representing a hydrogen atom, a metal atom, or a methyl group, in the formula (1-2), R 3 , R 4 , and R 5 each independently representing a hydrogen atom or a C1-C10 alkyl group, R 6 representing a C0-C10 alkylene group, X 3 representing a hydrogen atom, a metal atom, or a methyl group.

    摘要: [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).
