Abstract

A compact laminated ceramic electronic component having superior moisture resistance and electrical properties is provided. A laminated ceramic electronic component 1 includes an inner layer portion that contains a plurality of dielectric layers 2 a and internal electrode layers 3 comprising Ni as a main component that are laminated alternately, and a pair of dielectric outer layer portions 2 b which sandwich the inner layer portions. And Ni particles are segregated in the dielectric outer layer portions 2 b. And the amount of Ni particles existing in the dielectric layers 2 a is smaller than that in the dielectric outer layer portions 2 b.

Claims (3)

1. A laminated ceramic electronic component, comprising an inner layer portion that comprises a plurality of alternately laminated dielectric layers and internal electrode layers, and a pair of dielectric outer layer portions which sandwich the inner layer portion,

wherein the internal electrode layers comprise Ni as a main component, and wherein Ni particles are segregated in the dielectric outer layer portions, and

wherein when a distance between the internal electrode layers is a, the Ni particles segregated in the dielectric outer layer portions are located at a distance of a/2 or more apart from the position of the outermost internal electrode layer.
