Abstract: The present invention provides a molded electric part which does not include any lead wires and is preferably compact in size and light in weight. The molded electric part of the invention can effectively prevent deterioration of an electric element by molding the element with a resin. The invention is also directed to a method of simultaneously manufacturing a number of products having fixed dimensions and excellent electrical properties through injection molding with a multi-forming mold complex. A molded film capacitor (1) of the invention includes a film capacitor element (2) and an element-receiving body (3) mainly composed of a synthetic resin with high dielectric ability. The film capacitor element (2) is accommodated in an element-receiving recess (7) formed in a substantial center of the element-receiving body (3).

Abstract: A thin film capacitor having high performances, e.g. high frequency characteristics, heat resistance and dielectric strength, and capable of meeting demands for high integration and miniaturization of electronic devices, which comprises an electrically conductive substrate, a silica thin film formed on the substrate by bringing the substrate into contact with an aqueous solution of hydrosilicofluoric acid supersaturated with silica, and an electrically conductive film formed as an electrode on the silica thin film.

Abstract: A positive coefficient thin-film thermistor which is a thin film exhibiting a positive temperature coefficient (PTC) characteristic and having a thickness of 0.005 to 5 .mu.m and electrodes as constituting elements, and wherein the thin film is compound of a barium titanate based composition and the PTC characteristic is represented by a resistance variation in the transition of region of 1-10 orders of magnitude and a maximum resistance temperature variation rate of 1-20 orders/.degree.C.
