| Zusammenfassung: | To provide a capacitor having high electrostatic capacitance and high withstand voltage.SOLUTION: A capacitor includes a capacitor body 1 in which a plurality of dielectric layers 5 and internal electrode layers 7 are alternately laminated, and the dielectric layer 5 includes a plurality of metal particles 13a which are spaced apart from the surface of the dielectric layer 5 and have a metal particle row 13 arranged along the surface 5a. The metal particle 13a has a particle diameter of 0.2 μm or more and 0.4 μm or less, and the metal particle row 13 is separated from the surface 5a of the dielectric layer 5 by 0.4 μm or more.SELECTED DRAWING: Figure 1
【課題】 静電容量が高く、かつ耐電圧の高いコンデンサを提供する。【解決手段】 誘電体層５と内部電極層７とが交互に複数層積層されたコンデンサ本体１を備えており、誘電体層５は複数の金属粒子１３ａを含んでおり、該複数の金属粒子１３ａは誘電体層５の表面から離れた位置に、表面５ａに沿って列を成す金属粒子列１３を有している。金属粒子１３ａは粒径が０．２μｍ以上０．４μｍ以下であり、金属粒子列１３は誘電体層５の表面５ａから０．４μｍ以上離れている。【選択図】図１ |
