Summary:Provided is a ceramic electronic part which is able to improve reliability. According to the present invention, the ceramic electronic part comprises a laminated structure in which dielectric layers made of ceramic as the main ingredient and inner electrode layers are laminated in turn. For the dielectric layers, in a TSDC, the polarization temperature is set to be 150℃, the polarization electric field is set to be 15-20 V/㎛, the polarization time is set to be 60 minutes, and the temperature boosting speed is set to be 10℃/min. Here, when the peak current value on a low-temperature side with 160℃ or higher and lower than 230℃ is set to be IA and the peak current value on a high-temperature side with 230-350℃ is set to be IB, a relationship of IA/IB > 0.30 is established, and IB is equal to or lower than 100 pA/㎟. 신뢰성을 향상시킬 수 있는 세라믹 전자 부품을 제공한다. 세라믹 전자 부품은, 세라믹을 주성분으로 하는 유전체층과, 내부 전극층이 교대로 적층된 적층 구조를 구비하고, 상기 유전체층에 대하여, 분극 온도를 150℃로 하고, 분극 전계를 15V/㎛ 내지 20V/㎛로 하고, 분극 시간을 60min으로 하고, 승온 속도를 10℃/min으로 하는 TSDC에 있어서, 160℃ 이상 230℃ 미만의 저온측 피크 전류값을 IA로 하고, 230℃ 이상 350℃ 이하의 고온측 피크 전류값을 IB로 한 경우에, IA/IB>0.30의 관계가 성립되고, 또한, IB가 100pA/㎟ 이하인 것을 특징으로 한다.
