PROBLEM TO BE SOLVED: To provide a joining structure of optical parts, such as lenses or prisms or optical fibers, or optical waveguides, or optical glass or the like which does not give a deterioration by a laser beam of a high intensity or laser beam of a short wavelength in joining members used for adhesion when the optical parts are joined to members to be joined. SOLUTION: A light transparent thermosetting resin or polysiloxane solution, or a silicon compound solution, or siloxane solution is used as the joining member for bonding the optical parts and the members to be joined.
