Abstract
Lens surfaces are transferred by press-molding a glass material (16) by an upper mold (1) and a lower mold (2). After the lens surfaces are transferred, the outer circumferential portions of the upper and lower molds (1, 2) are clamped and pressed sideways to correct a shift between the optical axes of the transfer molding surfaces of the upper and lower molds (1, 2) and an inclination of the optical axes.
