Abstract:
A multilayer ceramic capacitor includes: a multilayer structure in which each of dielectric layers and each of internal electrode layers are stacked, wherein a relationship of 8.0≥IA/IB>1.40 is satisfied in a TSDC (Thermally Stimulated Depolarization Currents) of temperature elevation rate of 10 degrees C./min under a condition of 130 degrees C., 5 V/μm and a polarization of 30 min, when a peak current value on a lower temperature side in a temperature range of 130 degrees C. to 190 degrees C. is IA and a peak current value on a higher temperature side in a temperature range of 190 degrees C. to 280 degrees C. is IB.
