摘要

To make a mold releasing film hardly deteriorate the mold releasing performance even if high-temperature molding is repeated.SOLUTION: A mold release film 4 includes: a film body 2 made of a metal or alloy including a noble metal element and not melt at molding temperature; and a mold releasing agent 3 dispersed inside the film body 2 while being movable at a surface 2a that comes into contact with a molding material in the film body 2 at the molding temperature.SELECTED DRAWING: Figure 2
