Abstract
A conductive paste for an electrolytic capacitor used for connecting a cathode part and a cathode lead terminal of the electrolytic capacitor. The conductive paste includes a thermosetting resin, and conductive particles, and the conductive particles include flaky metal particles and acicular conductive particles. The content of the conductive particles in the conductive paste is, for example, 50 mass % or more and 70 mass % or less, and the mass ratio of the flaky metal particles to the total of the flaky metal particles and the acicular conductive particles is, for example, 60% or more and 80% or less.
