Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mold in which process of a mold is easy, high accuracy process of a transfer surface can be performed, moreover charging efficiency is high, moldability is improved, and cost reduction can be achieved; molding equipment; and a lens for optical communication that is molded.SOLUTION: A movable mold MM that molds a leg 21 of a lens 20 includes a first mold part MA and a second mold part MB that are splittable along an axial direction of the leg 21, thereby even if the leg 21 is long, the first mold part MA and the second mold part MB can be each formed by cutting work or the like by a separate process, thereby depending on an electric discharge process is not needed, and high accuracy process can be performed.
