The invention relates to a manufacturing method of a die for molding an optical element. The manufacturing method comprising: forming the first film layer of an amorphous alloy having a super-cooling liquid phase onto a master transfer surface of a master die for molding a molding transfer surface of the die; heating the first film layer more than a glass transition point of the amorphous alloy having the super-cooling liquid phase while a surface of the first film layer and a transferred surface of a base material of the die being faced and pressed; and peeling the first film layer from the master die and transferring the first film layer onto the base material of the die to form the molding transfer surface of the die.
