PROBLEM TO BE SOLVED: To provide an optical element which can form an image of high quality by a method different from the conventional art, and to provide a metallic die for molding the optical element and the manufacturing method of the metallic die for molding the optical element. SOLUTION: Since the device of a processing method can suppress radius of curvature of a circular-arc shape at the cross section of a boundary part forming section Mr small, the radius of curvature of the circular-arc shape at the cross section of a boundary section RL formed by transfer can be suppressed small. Thereby unnecessary light not used for imaging can be decreased and the image of high quality can be obtained. COPYRIGHT: (C)2008,JPO&INPIT |
