<P>PROBLEM TO BE SOLVED: To provide a fiber optic sensor cable for a distributed pressure sensor which can detect an accurate pressure value by compensating for changes in temperature and tensile force. Ž<P>SOLUTION: The fiber optic sensor cable for a distributed pressure sensor 1 includes: a tensile force compensation unit 2 having a tensile force compensation optical fiber 3; a temperature compensation optical fiber 7 which is spirally wound around its outside; an intermediate layer 8 for covering the outer periphery of the tensile force compensation unit 2 and the temperature compensation optical fiber 7; a foam layer 9 for covering the entire outer periphery of the intermediate layer 8; a skin layer 10 for covering the entire outer periphery of the foam layer 9; a pressure detection optical fiber 11 which is spirally wound around the skin layer 10; and a sheath 12 for covering the outer periphery of the skin layer 10 and the pressure detection optical fiber 11. The tensile force compensation unit 2 includes a tensile force compensation optical fiber 3 and a tensile strength member 4 therewithin, wherein the tensile strength member 4 is longitudinally accompanied by the tensile force compensation optical fiber 3, and the two are integrated within unit covering members 5, 6 in a solid manner.
