A hot runner nozzle for injection molding machine and a manufacturing method thereof are provided to achieve thermal equilibrium over the whole section of the nozzle since the nozzle body pipe is made of stainless steel superior in mechanical property and a heat balance pipe is made of copper material good in thermal conductivity. A hot runner nozzle(30) for injection molding machine, which receives resin from a manifold connected at one side and moves the resin into a mold and is wound with a heating pipe on the outside surface, comprises a body pipe which is made of stainless steel and has an installation hole, and a heat balance pipe(33) which is press-fitted to the installation hole of the body pipe and has a resin flow passage in the center.
