Abstract
In a thin film capacitor, a first electrode layerhas one or more regions B in which a distance Hbetween a boundary surface I of the first electrode layerand a dielectric layer, and a surface of the first electrode layer, becomes maximum, and an outer layerhas one or more regions T in which a distance Hbetween the boundary surface I and a surface of the outer layerbecomes maximum, as well as one or more regions t in which the distance Hbetween the boundary surface I and the surface of the outer layerdoes not become maximum. A projected area S, a projected area S, and a projected area S, satisfy equations (1) and (2):60%≤()  (1);60%≤()  (2).
