Abstract
A first inner electrode includes a 1-1 region, and a 1-2 region having a shorter dimension in a second direction than the 1-1 region and located closer to a third surface side than the 1-1 region. An end portion on the third surface side of a second inner electrode intersects with an end portion in the second direction of the 1-2 region when viewed in a lamination direction. A concentration of Sn or In or Au in the end portion in the second direction of the 1-2 region is higher than a concentration of Sn or In or Au in an end portion in the second direction of the 1-1 region.
