PROBLEM TO BE SOLVED: To provide a simple optical fiber sensor and a strain monitoring system using the sensor, not affected by a surrounding environment, capable of easily coping with multipoint operation, and requiring completely no power source. SOLUTION: This sensor is constituted from a plate spring mounted on a measuring object and deformed corresponding to the deformation quantity of the measuring object caused by an external force, an optical fiber Bragg grating for reflecting light having a prescribed wavelength, and an adhesive for fixing the optical fiber Bragg grating integrally along the longitudinal direction of the plate spring.
