PROBLEM TO BE SOLVED: To provide a method for spraying a mold release agent for a die-casting mold, which preferably sprays the releasing agent over the internal surface of a die-casting mold even with non-simple shape difficult to be sprayed. SOLUTION: The method for spraying the mold release agent for a die-casting mold includes: a reflector H which is arranged in the direction of an injection beam 7 of the agent and is heated to have the temperature beyond the nucleate boiling temperature, such as 160°C, of the agent; and a nozzle 4 for injecting the agent which injects the agent toward the reflector H with the heat kept in order to sprinkle the agent over a surface 9 with non-simple shape difficult to be sprayed of inner molds 3L and 3R, which seems like the reflector H reflects the agent. This method successfully brings the agent to the surface 9 with non-simple shape difficult to be sprayed and achieves to spraying the agent evenly over not only the end of the front section but also the side section of the surface with non-simple shape of the cavity 10 having narrow or uneven sections.
