Abstract: PROBLEM TO BE SOLVED: To steadily operate an optical fiber gyro under various environmental conditions by mounting a pair of leads consisting of optical fibers on a detection coil by a specified method using an adhesive having a low elastic coefficient. SOLUTION: Leads 100a, 100b consisting of a pair of optical fibers different in length are arranged on the circumference 108 of a detection coil 102 so as to extend in different directions, and the long lead 100a is bent after extended along the circumference 108 and extended in the same direction as the short lead 100b. An adhesive material having a low elastic coefficient, for example, less than about 500 psi, is applied and hardened by UV irradiation to initially adhere the leads 100a, 100b to the coil 102, and the leads are wound adjacently around the circumference 108 in the same circumferential direction. Thereafter, the same adhesive material is applied to the whole outer surface 118 of the wound leads and hardened. The stress can be dispersed by the use of the adhesive material having low elastic coefficient, and the removal of the leads is also facilitated.
