Abstract
A method of producing an optical element, which includes a glass substrate and a sheet-like formed body, is provided. The sheet-like formed body is formed of an organic resin, one surface of which has a fresnel lens pattern and the other surface of which is bonded to the glass substrate. The sheet-like formed body is a thermoplastic polymer composition. A bonding surface of the sheet-like formed body facing the glass substrate is treated by irradiating active energy. A bonding surface of the glass substrate facing the sheet-like formed body is bonded to the bonding surface of the sheet-like formed body by using a silane coupling agent as a crosslinking agent.
