A multilayer ceramic capacitor includes an inner layer portion including inner dielectric layers and inner electrode layers, and outer layer portions sandwiching the inner layer portion in a stacking direction. When a region between the first inner electrode layer at a center in the stacking direction and a fifth inner electrode layer from a first inner electrode layer at the center in the stacking direction toward the outer layer portion side is a region A and when the region between the first inner electrode layer closest to an outer layer portion side and the second inner electrode layer from the first inner electrode layer closest to the outer layer portion side toward the center in the stacking direction is a region B, a standard deviation of the ceramic grain diameters in the region A is larger than a standard deviation of the ceramic grain diameters in the region B.
