A conductive paste obtained by adding an organic solvent B to a vehicle containing a Ni powder, a binder resin component, and an organic solvent A. The Ni powder has an average primary particle size of 30 to 400 nm. The binder resin component is cellulose acetate butyrate. Organic solvent A is a solvent having a &#x394; &#x3b4; value of 11.5 or less with the cellulose acetate butyrate. Organic solvent B is a solvent having a &#x394; &#x3b4; value from 11.5 to 25.0 with the cellulose acetate butyrate. A ratio of the organic solvent B relative to a total of the organic solvent A and the organic solvent B is 5.0 to 40.0 wt %.

Conductive paste and ceramic electronic component

A conductive paste that includes a (meth)acrylic resin serving as a binder resin, an organic solvent, and a metal powder. The (meth)acrylic resin has a glass transition point Tg in the range of &#x2212;60&#xb0; C. to 120&#xb0; C., a hydroxyl group content in the range of 0.01% to 5% by weight per molecule, an acid value in the range of 1 to 50 mgKOH/g, and a weight-average molecular weight in the range of 10,000 to 350,000 Mw.
