MULTILAYER CERAMIC CAPACITOR AND MULTILAYER CERAMIC CAPACITOR SERIES INCLUDING THE SAME, AND MULTILAYER CERAMIC CAPACITOR MOUNTING BODY

摘要

PROBLEM TO BE SOLVED: To provide a multilayer ceramic capacitor that further suppresses generation of cracks and the occurrence of a short circuit due to cracks than ever before.;SOLUTION: A laminate body of a multilayer ceramic capacitor includes: in a lamination direction, a first outer layer portion 12b₁ that is a dielectric layer positioned nearest to the first principal surface side 111; a second outer layer portion 12b₂ positioned nearest to the second principal surface side 112; and an inner layer portion 11m that is positioned between the first outer layer portion and the second outer layer portion and includes a conductor layer nearest to the first principal surface and a conductor layer nearest to the second principal surface. The second outer layer portion includes: an outside outer layer portion 12b₂₂ having the second principal surface and an inside outer layer portion 12b₂₁ positioned between the outside outer layer portion and the inner layer portion. At least part of the dielectric layer includes a plurality of pores. In a cross section passing through the center of the laminate body, when a total value of a cross section area of the pore per unit area of the dielectric layer configuring the outside outer layer portion is defined as So and a total value of a cross section area of the pore per unit area of the dielectric layer included in the inner layer portion is defined as Sa, the relationship: So/Sa≤1 is satisfied.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
