PROBLEM TO BE SOLVED: To provide an optical element improving durability of a mold by reducing demolding force in starting demolding, controlling a start point and a direction of the demolding, and preventing peeling, deformation and breakage of a resin from a glass base material, and to provide its manufacturing method. SOLUTION: The optical element forms the energy curable resin having a required shape on a base material by dropping the energy curable resin into the mold, installing the base material thereon, and applying energy on the resin to be cured and demolded. It has a projection-like part in viewing from the orthogonal direction to a base material face on an outer peripheral part of a molding. In addition, the projection-like part is made a demolding start point in the manufacturing method of the optical element forming the energy curable resin having a required shape on the base material by dropping the energy curable resin into the mold, installing the base material thereon, and applying energy on the resin to be cured and demolded.
