Laminated ceramic electronic component

Abstract

A laminated ceramic capacitor with a laminated body including a plurality of stacked ceramic layers and internal electrodes located between the ceramic layers. The laminated body has a pair of mutually opposed principal surfaces extending in the direction in which the ceramic layers extend, a pair of mutually opposed side surfaces and a pair of mutually opposed end surfaces which respectively extend in directions orthogonal to the principal surfaces. The internal electrodes are 0.4 μm or less in thickness, and are located in an area defined by a width-direction gap of 30 μm or less interposed with respect to each of the pair of side surfaces and an outer layer thickness of 35 μm or less interposed with respect to each of the pair of principal surfaces.
