Abstract
A measuring method for measuring a concentration of a donor element which is solid-solved in ceramic grains of a plurality of ceramic dielectric layers, includes measuring (a current value at 10 V/μm when a direct voltage is applied to a plurality of ceramic dielectric layers at 125 degrees C.)/(a current value at 10 V/μm when a direct voltage is applied to the plurality of the ceramic dielectric layers at 85 degrees C.), with respect to a multilayer ceramic capacitor having a multilayer structure in which each of the plurality of ceramic dielectric layers and each of a plurality of internal electrode layers are alternately stacked.
