发明名称 MULTILAYER CERAMIC CAPACITOR
摘要 Disclosed is a multilayer ceramic capacitor exhibiting excellent reliability in high-temperature load test even when a dielectric layer is formed thin. Specifically disclosed is a multilayer ceramic capacitor comprising a plurality of dielectric layers (5) composed of barium titanate crystal grains (11) having a pore (13) in a crystal grain, a plurality of internal electrode layers (7) formed between the dielectric layers (5), and an external electrode (3) electrically connected to the internal electrode layers (7). In this multilayer ceramic capacitor, the barium titanate crystal grains (11) has a core-shell structure which is composed of a core portion (11a) and a shell portion (11b) formed around the core portion (11a) and having a lower tetragonal ratio than the core portion (11a), and the pore (13) is mainly formed in the core portion (11a).
