Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fiber-optic gyroscope which prevents Lorentz reciprocity and the performance of gyroscope from degradation. SOLUTION: Method for constructing this fiber-optic gyroscope includes optical combination of the first optical fiber 210 and the second optical fiber 220, with the optical path of an interferometer 200 having external surface; optical combination of at least a part of these first optical fiber 210 and second optical fiber 220 with the external surface; and optical combination of those first optical fiber 210 and second optical fiber 220 with the optical path of integrated optical chip (IOC).
