    Abstract: In a method of manufacturing a glass optical element by press-forming a glass material in a chamber by using a forming mold comprising upper and lower dies at least one of which is movable, where a surrounded space is formed between the glass material and at least one of the upper and the lower dies when the upper and the lower dies come into contact with the glass material, a pressure within the chamber is reduced before the glass material placed in the forming mold is heated to a press-forming temperature. After sealing the space as formed when the glass material is in contact with at least one of forming surfaces of the upper and the lower dies, a gas is introduced into the chamber. The glass material is heated in the gas and then press-formed under a pressing load.
