Abstract

A multilayer ceramic capacitor includes an element body. The element body includes a stack of first internal electrode layers, dielectric layers and second internal electrode layers. The element body has a first surface and a second surface opposite the first surface. The multilayer ceramic capacitor also includes a first external electrode formed on the first surface of the element body and a second external electrode formed on the second surface of the element body. The first internal electrode layer has a first current path extending in a first plane perpendicular to the first surface such that the first current path has a shorter component on the first plane in a first direction toward the first surface than in a second direction perpendicular to the first direction. The second internal electrode layer has a second current path that possesses a similar anisotropy to the first internal electrode layer.
