An air passing mold member, which constitutes the cavity inner surface 1a at the connection part of the cavity and the gas passage and permits the passage of the gas between the cavity and the gas passage, is mounted in the connection part of the cavity and the gas passage. The air passing mold member has an air passing layer 13, which comprises the cylindrical holder member provided to the connection part and the porous body installed in the holder member so as to be partially exposed to the cavity, and a support member 14 for supporting the air passing layer 13 from the gas passage side.
