A multilayer ceramic capacitor 1 having a dielectric layer 2 mainly composed of barium titanate or barium calcium titanate. When the dielectric layer is barium titanate, the proportion of particles having a thickness of 1 nm or less of the grain boundary 22 existing between adjacent dielectric particles 20 among the plurality of dielectric particles 20 forming the dielectric layer 2 is 30 in total. It is more than 95%. In the case where the dielectric layer 2 is barium calcium titanate, the ratio of the grains of the grain boundary 22 existing between the adjacent dielectric particles 20 among the plurality of dielectric particles 20 forming the dielectric layer 2 is 1 nm or less. 20% or more and 70% or less of this whole. |
