Dry film of conductive paste

Abstract

This invention provides a dry film of a conductive paste for internal electrodes, which improves reliability in high-temperature load tests by improving the distribution of metal and ceramic particles in a dry film obtained from a conductive paste containing metal particles, ceramic particles, and resin. The dry film of the conductive paste is obtained by drying a coating film containing a conductive paste containing metal particles, ceramic particles, and resin. The metal particles and ceramic particles are mixed on the surface of the dry film. For the surface, a plurality of quadrilateral regions are provided, with the number of ceramic particles in each region being at least 1.5 times and less than 5 times the average particle diameter of the metal particles. The coefficient of variation obtained by the standard deviation of the average number of ceramic particles in each quadrilateral region and the number of ceramic particles in the plurality of quadrilateral regions is at least 10% and less than 30%.
