PROBLEM TO BE SOLVED: To provide a method which can mold a high precision lens with quality dispersion controlled and curtail a time for molding one lens, and a mold. SOLUTION: In the method for molding the lens using the mold 1 for molding the lens by injecting a resin material into a cavity 11 formed in the mold composed of a movable mold 3 and a fixed mold 2 through an injection process for injecting the resin material of a prescribed temperature into the cavity 11, a pressure holding process, a cooling process, and a take-out process, inserts 7 and 10 having transfer surfaces 6 and 9 facing the cavity 11, a heating means for heating the transfer surfaces, an insulating means for holding the heat of the transfer surfaces temporarily, and a cooling means for transmitting the heat of the cavity outside the mold are installed, a cooling time is curtailed by injecting the resin material of a lower temperature, and a fine transfer can be performed precisely and surely by heating the transfer surfaces 6 and 9 facing the cavity 11.
