PROBLEM TO BE SOLVED: To provide an optical fiber sensor cable, capable of accurately detecting deformations with itself buried in a structure, that has improved durability, and capable of performing distortion monitoring for a long time without the cable moving, even when it is in concrete. SOLUTION: The optical fiber sensor cable has its structure of covering altogether with a cable sheath an optical fiber for detecting distortion, a protective pipe within which an optical fiber for temperature compensation is stored loosely, and a tensile strength body. The cable sheath has its cross-sectional shape of connecting via a neck part a measuring part, within which the optical fiber for detecting distortion and the protective pipe are buried and a tensile strength body storing part, within which the tensile strength body is buried, as well as, the neck part has multiple window parts along its longitudinal direction.
