A molded product from a mold, the mold for molding a molded product in a desired shape can be designed with high precision by correcting a shape change of the molded product. A mold in which use surfaces of an upper mold and a lower mold are formed to be design curved surfaces of an optical lens is prepared. A curved surface shape of the optical lens molded from this mold is measured, and a measured value is approximated by equation (1). The curved surface of the optical lens specified by the equation and a design curved surface are compared to obtain an error between both the curved surfaces. Information corresponding to the error is used as correction information, and the use surfaces in the upper mold and the lower mold are corrected and designed..times..times..rho..times..times..rho..times..times..times..rho.- .times. ##EQU00001##
