摘要： A method for manufacturing a glass optical element includes the steps of: feeding molten glass onto a lower mold part; and compression-molding the molten glass using an upper mold part and the lower mold part. The upper mold part is provided with a recess for forming a positioning protrusion of the glass optical element. A surface of the recess includes a first region where a protective film against the molten glass is formed, and a second region where the protective film is not formed and the upper mold part is exposed. In the step of compression-molding the molten glass, after the molten glass enters the recess, the molten glass is compression-molded in a state where a part of the molten glass and the second region do not contact each other, to thereby form the positioning protrusion of the glass optical element.
