ABSTRACT:
The present invention provides a resin-cemented optical element comprising a base member10and a resin layer11formed on the surface of the base member; the resin layer11being in a thickness of 300 μm or smaller at least at some part of a peripheral portion (i.e., a region within 1 mm from the peripheral edge face17of the resin layer11, or a region outside an effective-diameter region), and being in a thickness12of 850 μm or larger at a position which is thickest in the resin layer; a mold therefore; a manufacturing method thereof; and an optical article having this optical element.
