摘要： Parts of a base film that correspond to respective movable contacts are formed into projections. Operating projections each including a projecting member fixed to a top surface of the base film by an adhesive resin are formed and correspond to the movable contacts, respectively. The adhesive resins have different fixed diameters.

摘要： Movable contact unit of the present invention comprises a plurality of dome-like movable contacts made of electrically conductive metal sheets capable of making an inflective action when depressed, a base film having an adhesive layer for retaining upper surfaces of the plurality of movable contacts, and a plurality of press-down projections bonded by adhesive to an upper surface of the base film in positions corresponding to center portions of the respective movable contacts, wherein the upper surface of the base film and underside surfaces of the press-down projections are each provided with a pretreated layer. The above structure has an advantage of strengthening the bonding between the adhesive and each of the pretreated layers formed on the adhering surfaces of the base film and the press-down projections, so as to provide the movable contact unit with outstanding reliability in maintaining the bonded condition for a long duration.

摘要： Disclosed is a method of efficiently bonding bump members of a small cylindrical shape punched out of a highly flexible plastic film without leaving considerable extent of cutting burrs. The method comprises steps of forming bump members 45 by carrying out a half-cut process on first substrate 56 comprising highly flexible first plastic film 51 adhered to first reinforcing film 53 of a material having rigidity higher than first plastic film 51 with adhesive layer 52, removing first plastic film 51 in a manner to leave cut-out bump members 45 on first reinforcing film 53, adhering bump members 45 to second plastic film 61 coated with adhesive 47, and securely bonding thereafter bump members 45 to second plastic film 61 by hardening adhesive 47.
