PURPOSE: A method for manufacturing an exothermic pipe using synthetic resin semiconductor is provided to apply the exothermic pipe into a house heating apparatus and to apply the exothermic pipe to the construction of an agricultural vinyl house. CONSTITUTION: A mixture(3) of high density synthetic resin material, a pyrogen material, and a semiconductor material is extruded from a screw(7) provided in a cylinder(5). The cylinder also has a heater(6) for melting the mixture. The extruded high density pyrogen synthetic resin mixture is attached to an electric wire(2) passing a pyrogen coating dice(9). The electric wire coated with the high density pyrogen synthetic resin is molded to form an exothermic wire(11). Finally, an alloplasm is added to the exothermic wave dehydrated at cooling vacuum device to prevent the adsorption of another synthetic resin.
