A method for manufacturing a lens which includes raised portions arranged on a surface of the lens with a pitch smaller than or equal to a predetermined pitch, and is configured to reduce reflection of light having a wavelength longer than or equal to the predetermined pitch includes preparing a molding die in which recessed portions corresponding to the raised portions are formed, filling a molten resin material into a cavity of the molding die via a gate, and curing the resin material in the molding die. The molding die includes a peripheral region in a periphery of the gate, and an adjacent region adjacent to the peripheral region. First recessed portions in the peripheral region are deeper than second recessed portions in the adjacent region.
