Abstract:
A method of making a synthetic resin window plate, the method comprising the steps of:(a) applying a conductive paste onto one of sides of a thermoplastic transparent film and curing said paste thereon to form a plurality of lines as well as a pair of electrodes such that one ends of said lines are integral with one of the electrodes, with the other ends of said lines being integral with the other electrode;(b) then disposing the transparent film in a cavity of an injection mold such that the other side of the transparent film does fully contact and stick to a wall of the cavity of said mold;(c) subsequently injecting a further thermoplastic resin into said cavity so that a base is formed to have voids where portions of the electrodes are exposed to provide terminal portions, such that the transparent film is bonded to the base; and(d) finally taking out of the injection mold the base together with the transparent film bonded thereto, before securing an electric contact member in each void so as to be integral with the terminal portion.
