摘要:
A multilayer ceramic capacitor having an internal electrode layer and a dielectric layer having a thickness of less than 2 μm is provided, wherein the dielectric layer contains a plurality of dielectric particles, and when it is assumed that standard deviation of a particle distribution of the entire dielectric particles in the dielectric layer is σ (no unit), an average particle diameter of the entire dielectric particles in the dielectric layer is D50 (unit: μm), and a rate that dielectric particles (coarse particles) having an average particle diameter of 2.25 times of the D50 exist in the entire dielectric particles is p (unit: %), the σ and p satisfy σ
