A thin-film capacitor includes a lower electrode film, a high dielectric film and an upper electrode film disposed sequentially. One film of the three films includes first and second edge portions placed opposite to each other. Furthermore, the one film includes a first opening which extends from the first edge portion toward the second edge portion and a second opening which extends from the second edge portion toward the first edge portion. Also, the first and second openings are respectively terminated away from the second and first edge portions. Alternatively, one film of the three films includes a plurality of edge portions which configure an outline of the one film. Furthermore, the one film includes a plurality of openings which respectively extend therethrough and which are terminated away from all the edge portions. Also, there is provided a manufacturing method of the thin-film capacitor.
