A rotating non-axisymmetric lens manufactured by polishing using a processing tool and a molding die thereof, and a manufacturing method of a rotating non-axisymmetric mirror and a forming die thereof are provided. A rotational non-axisymmetric lens partially including a rotational non-axisymmetric surface and a molding die thereof, and a rotational non-axisymmetric mirror partially including a rotational non-axisymmetric surface and a molding method thereof When forming a rotation non-axisymmetric surface while scanning the surface of the workpiece with the grinding or cutting means, grinding or cutting of the rotation non-axisymmetric surface by the grinding or cutting means is performed. This is performed while scanning while moving in the direction along the meridional plane.
