Abstract
A lens molding apparatus (100) of the present invention includes: a mold (1) having a transfer surface (1a) for transferring a predetermined lens shape to a resin material; a mold (2) having a transfer surface (2a) for transferring a predetermined lens shape to the resin material; a support device (3) for moving the mold (1); a heating device (4) curing the resin material so as to form a lens, the resin material having been supplied between the transfer surface (1a) and the transfer surface (2a); and an ultrasonic vibrator (5) applying vibration from a side surface of the mold (1 or 2) so as to form a gap at least at a part between the transfer surface (1a or 2a) and the lens.
