PROBLEM TO BE SOLVED: To improve mold releasability of a molding by installing an ejector pin in a mold using a lease film and to adsorb/hold a release film covering the ejector pin protruding from a mold parting surface by sticking it following the mold parting surface around the tip protrusion of the ejector pin. SOLUTION: The mold 100, with the release film 180 covering the ejector pin 140 protruding from the mold parting surface in a mold opening state sucked into an air suction passage through a clearance 190, is stuck following the mold parting surface around the tip protrusion of the ejector pin 140 to be adsorbed/held.
