PURPOSE: A heating runner nozzle is provided to secure the reliable operation, to be produced cheaply and to be installed quickly. CONSTITUTION: A material pipe(20) is produced by a material of high strength. At least one flow duct(30) is offered therein by installing on a manifold. A heater(40) is offered under a nozzle tip and stuck to the outer circumference for a melting material of the material pipe. The heater is produced by a high thermal conductive material. The heater contains a first accepting channel(43) for the material pipe and another accepting channel(45) for a linear heating element(50). The channel(45) is in parallel with the first accepting channel. Thereby, a heating runner nozzle is separately inserted into the heater and replaced without a special dismantling operation.
