Provided is an optical part comprising an optical lens made of a transparent resin and a resin holder for holding the optical lens. The optical part can be manufactured by two-color molding, the bonding state between the optical lens and the holder is excellent, and the optical part does not experience a decline in positional accuracy during use due to having high slideability and anti-abrasion properties. The optical part is characterized in comprising an optical lens or mirror made of a thermoplastic transparent resin, and a holder for holding the optical lens or mirror, and is characterized in that the optical lens or mirror is thermally bonded to the holder, and the holder is mainly made of the same thermoplastic transparent resin as the optical lens or mirror and contains a solid lubricant. |
