Abstract
The capacitor includes a dielectric body portion including ceramic layers and internal-electrode layers laminated in an alternating manner, and a cover portion provided in a periphery of the dielectric body portion. The cover portion includes pores. A part of the cover portion located in a position in a direction perpendicular to a lamination direction of the ceramic layers and the internal-electrode layers is a side surface cover portion. When the side surface cover portion is divided into three equal regions in a width direction, the regions being a dielectric body portion-side region, a central region, and a surface-side region, the number of the pores is higher in the dielectric body portion-side region than in the central region and the surface-side region.
