Abstract
(EN)
Provided is a conductive paste or the like which has excellent dispersibility. This conductive paste comprises conductive powder, ceramic powder, a dispersant, a binder resin, and an organic solvent, wherein: the dispersant includes a first acidic dispersant and a second acidic dispersant; the first acidic dispersant has an average molecular weight of 500-2000 (exclusive of 500) and has at least one hydrocarbon group-containing branched chain with respect to a main chain; the second acidic dispersant has a carboxyl group other than the first acidic dispersant; the binder resin includes an acetal-based resin; and the organic solvent includes a glycol ether-based solvent.
