Abstract: A method for producing an optical element by bonding a plurality of optical member with an adhesive, which is capable of providing the optical element with sufficient optical performance and with such a sufficient bonding strength to prevent separation from being made at bonded portions, and of making alignment easily, is provided. The method for producing an optical element, which comprises bonding two or more optical members with an adhesive, is characterized in that at least one of confronting bonded surfaces on at least one pair of contact surfaces of the optical members is subjected to dry cleaning in such a state that at least a surface connecting to a bonded surface is masked, followed by applying a liquid adhesive as the adhesive on the cleaned surface and curing the liquid adhesive to bond the optical members.
