Abstract:
A multilayer ceramic capacitor includes first dielectric ceramic layers each with a thickness of about 0.48 μm or more and about 0.50 μm or less in the lamination direction, and additional dielectric ceramic layers each with a thickness of about 10 μm or more and about 15 μm or less in the width direction. A number of dielectric particles in each first dielectric ceramic layer in a thickness direction is three or more and six or less. A number of dielectric particles in each additional dielectric ceramic layer in a thickness direction is 100 or more and 150 or less. When the number of dielectric particles in each of first dielectric ceramic layer is NT, and the number of dielectric particles in each additional dielectric ceramic layer is NW, a ratio of NT to NW is about 1:23.08 or more and about 1:46.15 or less.
