Abstract

To provide a thin-film capacitor capable of improving the stability of electric connection between an internal electrode layer and a connection electrode. The thin-film capacitor comprises: two or more dielectric layers deposited above a base electrode; an internal electrode layer being deposited between the dielectric layers and having a projecting portion which projects from the dielectric layer when seen from a laminating direction; and a connection electrode electrically connected to the internal electrode layer via at least a part of a surface and an end face of the internal electrode layer included in the projecting portion, wherein a ratio L/t between a projection amount L of the projecting portion of the internal electrode layer with respect to the dielectric layer and a thickness t of the internal electrode layer is 0.5 to 120.
