An optical fiber 1 includes a core 11 and a cladding material 12. In a collision detection optical fiber sensor 100, a plurality of linear members 2 and 3 are twisted around an outer periphery of the cladding material 12 of the optical fiber 1. An elastic member 6 of the liner member 2 has an elasticity different from that of an elastic member 7 of the first linear member 3. The hardness of the elastic member 6 is lower than that of the elastic member 7. A rubber hardness difference measured by a durometer type A according to a JIS K6253 between the elastic member 6 and the elastic member 7 is not less than 10.

A collision detection system includes a shock detecting device, a collision position detecting device, a correcting device, and a collision determining device. The shock detecting device detects a magnitude of a shock due to a collision. The collision position detecting device detects a collision position of the collision. The correcting device corrects a detection result detected by the shock detecting device based on a detection result detected by the collision position detecting device. The collision determining device determines the collision based on a corrected result corrected by the correcting device.
