Abstract
An optical device includes a rigid pipe provided to cover the outer peripheries of a fixing joint portion and an optical fiber. The tip portion of the rigid pipe has a gap for providing flexibility between the optical fiber and the tip portion. Therefore, the rigid pipe suppresses bending of the optical fiber to avoid concentration of stress in the fixing joint portion for fixing the optical fiber to an optical unit section, thereby avoiding breakage of the optical fiber in the fixing joint portion.
