PROBLEM TO BE SOLVED: To provide a molding die capable of equalizing the quality of moldings. ! SOLUTION: A molding die (8) comprises a cavity piece (3) which has an optical surface non-molding surface (6) at least partially, at least one injection vent hole (14) for blowing a gas (13) toward a resin (10) and at least one discharge vent hole (15) for discharging the gas (13) blown toward the resin (10). When the optical surface non-molding surface (6) of the cavity piece (3) is slid so as to be separated from the resin (10), the gas (13) blown toward the resin (10) from the injection vent hole (15) is discharged through the discharge vent hole (15). !
