ABSTRACT:
An antifogging window plate has a transparent film and a base both made of thermoplastic resins. Conductive lines and electrodes are printed using a conductive paste on one side of the film, which is then bonded to the base. One portion of each electrode is exposed as a terminal portion to be connected to an electric contact member. The window plate is made by injection molding with the surface of the film opposite from the printed surface being in contact with the cavity wall of the mold, so that the integration of the film with the base is effected simultaneously with the forming of base. Each contact member is subsequently fitted in an injection-molded void facing the terminal portion, or is secured in place at the same time as the injection molding.
