A structure deterioration detection system includes an optical fiber cable that is placed along the longitudinal direction of a structure and continuously detects any vibration along the longitudinal direction of the structure, and a signal processing unit including a vibration measurement unit that measures the strength of a detected vibration, a per unit time integration unit that integrates the vibration strength for a specified period of time, an information storage unit that stores the integrated vibration strength, and a deterioration determination unit that makes a determination about whether deterioration of the structure has occurred by comparing the integrated vibration strengths at different times.
