Abstract
A ceramic electronic device includes a multilayer structure in which each of a plurality of dielectric layers and each of a plurality of internal electrode layers are alternately stacked. A relationship of 'I/I>0.30' is satisfied and a peak current value Iis 100 pA/mmor less in a TSDC in which a polarizing temperature is 150 degrees C., a polarizing electric field is 15 V/μm to 20 V/μm, a polarizing time is 60 minutes, and an increasing speed of temperature is 10° C./minute, when a peak current of a low temperature side of a temperature range of 160 degrees C. or more and less than 230 degrees C. is Iand a peak current of a high temperature side of a temperature range of 230 degrees C. or more and 350 degrees C. or less is I.
