Abstract

A multilayer ceramic capacitor includes a laminate and an external electrode. The laminate includes a central layer portion in which first and second internal electrode layers are alternately laminated with a dielectric ceramic layer therebetween, a peripheral layer portion sandwiching the central layer portion in a lamination direction, and a side margin sandwiching the central layer portion and the peripheral layer portion in a width direction. When viewing the laminate and the first external electrode through a cross-section parallel to the width direction and the lamination direction at a central portion in a length direction of the first external electrode, W>Ris satisfied and T>Ris satisfied.
