Abstract
A molded product which is molded with thermoplastic resin by a thermal deposition method. The method uses a substantially ring-shaped resistance heating element. A hole is provided for impressing the voltage by inserting the electrode from this hole and impressing the voltage to the resistance heating element. Thereafter the hole is blocked. The electric resistance heating body is disposed between the composition planes of the parts which are to form a body.
