LAMINATED CERAMIC ELECTRONIC COMPONENT

摘要

A multilayer ceramic electronic component including a ferrite ceramic laminate having a multilayer structure is disadvantageously brittle because of a fundamental feature of ferrite. A ceramic laminate (5) is constituted by a ceramic base layer (2) and ceramic auxiliary layers (3 and 4) arranged on both main surfaces of the ceramic base layer (2), the ceramic base layer (2) and the ceramic auxiliary layers (3 and 4) being formed by co-firing. The ceramic base layer (2) and the ceramic auxiliary layers (3 and 4) are composed of ferrite materials having the same compositional system and have substantially the same crystal structure. The linear expansion coefficient of the ceramic auxiliary layers (3 and 4) is smaller than the linear expansion coefficient of the ceramic base layer (2).
