Abstract: A thin film capacitor comprises: a laminated body in which a dielectric layer and an upper electrode layer are successively laminated on a base electrode; a protective layer that covers a part of the base electrode, the dielectric layer and the upper electrode layer and includes a through-hole respectively on the base electrode and on the upper electrode layer; and terminal electrodes that are electrically connected with the base electrode and the upper electrode layer through the through-holes of the protective layer, and a modulus of longitudinal elasticity (Young's modulus) of the protective layer is 0.1 GPa to 2.0 GPa.
