Patent ID: 7839651

Claim:
A multilayer ceramic electronic component comprising: a ceramic laminate having a multilayer structure including a ceramic base layer made substantially entirely of a polycrystalline phase with no amorphous phase and at least one ceramic auxiliary layer, the ceramic base layer and the at least one ceramic auxiliary layers being co-fired, the at least one ceramic auxiliary layer being arranged on at least one main surface of the ceramic base layer and being made substantially entirely of a polycrystalline phase; and at least one conductive pattern arranged inside or on an outer surface of the ceramic laminate; wherein the polycrystalline phase in the ceramic base layer and the polycrystalline phase in the at least one ceramic auxiliary layer have substantially the same crystal structure; and the at least one ceramic auxiliary layer has a linear expansion coefficient α 2 that is less than the linear expansion coefficient α 1 of the ceramic base layer.
