PROBLEM TO BE SOLVED: To provide a lens molding mold which has a simple configuration and controls the coma-aberration by preventing a deviation of the optical axis in the upper and the lower lens molding plane so as to improve the optical characteristics. SOLUTION: The lens molding mold is constructed by processing an upper mold housing section 6 and a lower molding housing section 13 simultaneously with an upper mold plate 4 and a lower mold plate 5 assembled, by engaging the upper mold 9 in the upper mold housing section 6 and the lower mold 16 in the lower mold housing section 13, respectively, and by fixing the resultant bodies in order to control the deviation of the optical axes of the upper lens molding plane 12 and the lower lens molding plate 19.
