Abstract:
1. A screening method for laminated ceramic capacitors, wherein the laminated ceramic capacitor has a plurality of internal electrodes embedded in a dielectric base substance in a stratified manner, the internal electrodes being caused to conduct to a pair of terminal electrodes provided on an outer surface of the dielectric base substance, the terminal electrode having an outermost layer containing Sn as a main component; the laminated ceramic capacitor is set in a temperature environment which is not less than 125° C. and not more than 180° C.; a step of applying a direct-current voltage between the terminal electrodes in order to measure a direct-current insulation resistance is included; the step of applying the direct-current voltage includes a first step and a second step; a direct-current voltage V a direct-current voltage V
