Abstract: Multilayer smectite capacitor (MLSC) provided with a new dielectric film, and a first electric and second electrode formed sandwiching it and facing each other, wherein has dielectric film. The dielectric film in this capacitor is smectite, and either or both of said first electrode and second electrode contain at least one metal selected from group consisting of Cu, Ni. Thin internal conductors are each placed between the smectite dielectric layer and arranged in parallel. The smectite dielectric layers have a thickness of about 0.6 to less than 2 micrometer. The internal conductors have a thickness of about 0.2 to 0.4 micrometer.
