Abstract

The present invention provides a conductive paste which leaves less fine undissolved matter when dissolved in an organic solvent and thus can be easily filtrated, which has excellent printability, and which can exhibit excellent surface smoothness after printing. Provided is a conductive paste used for forming an electrode of a multilayer ceramic capacitor, the conductive paste containing: a polyvinyl acetal resin; an organic solvent; and a conductive powder, the polyvinyl acetal resin having a wave number A (cm) of a peak within a range of 3,100 to 3,700 cmin an IR absorption spectrum measured using an infrared spectrophotometer; and a hydroxy group content (mol %), the wavenumber A of the peak and the hydroxy group content satisfying relations of the following formulas (1) and (2):[(3,470−)/Hydroxy group content]≤5.0  (1)(3,470−)≤150  (2)wherein A is a wavenumber which is lower than 3,470 cmand at which a transmittance a (%) satisfying [100−(100−X)/2] is exhibited, where X (%) is s minimum transmittance of the peak within the wavenumber range of 3,100 to 3,700 cm.
