Document Type and Number:
WIPO Patent Application WO/2023/218955
Kind Code:
A1
Abstract:
Provided is a laminated ceramic capacitor having high reliability while still being compact and having a large capacity. A laminated ceramic capacitor 1 has a laminated body 10 provided with: an internal layer section 30 formed by alternately layering a plurality of dielectric layers and internal electrode layers; and a pair of side margin sections 42 that sandwich the internal layer section in the width direction. When the laminated body is cut at a center position in the length direction and viewed in a cross section that is defined by the width direction and the lamination direction, a crystalline oxide containing at least one of Al, Mg, and Si is present in the side margin sections 42 as an elongated secondary phase with an aspect ratio of 5 to 20 inclusive.
