To enable a film to be adhesion-coated on a surface of a mold for compression molding without being wrinkled, in compression molding using the film.

A mold for compression molding includes a lower mold 1A and a upper mold 1B constituting a cavity C, a first suction groove 5 for sucking and holding a mold release film 4 and a second suction groove 6 sucking the mold release film 4 inside the first suction groove 5 radially are provided in a upper surface being a cavity outside, of the lower mold 1A. A groove side surface s2 on the cavity side in the second suction groove 6 is formed into an inclined surface more gentle than that of a groove side surface s1 on the outside radially to make a cross section shape of the second sucking groove 6 be inside/outside asymmetrical and widened upward.
