PROBLEM TO BE SOLVED: To enable to form a continuous shape on a molding face with good accuracy by an impression processing method. SOLUTION: The molding face is formed on a matrix, and an impression processing is applied on the molding face. Then, a metal mold matrix 1B for manufacturing an optical element being an inverted shape of the matrix impression-processed is obtained by an electroforming method. Thereafter, the impression processing is applied on the flat face part 1d of the molding face 1a of a metal mold matrix 1B for manufacturing the optical element, to form an inverted shape of a micro-prism array on the molding face 1a of a metal mold 1 for manufacturing the optical element.
