Abstract
A method of producing an optical component includes a transfer step of sandwiching a molding material layer of a molding material between a thin glass plate and a mold and transferring an indented pattern on the mold to the molding material layer to form a patterned indented layer on the thin glass plate, and a separation step of separating the mold from the patterned indented layer. During the transfer step, a reinforcing plate is removably attached to the thin glass plate.
