<p>PROBLEM TO BE SOLVED: To provide a metal tube optical fiber cable capable of obtaining a highly accurate measurement value, when used as a sensor for measuring a physical quantity of a strain distribution, by gluing an inner peripheral surface of a metal tube and a filler material together with a high degree of adhesion.SOLUTION: A metal tube optical fiber cable 1 comprises an optical fiber core wire 3 and a filler material 4 accommodated together inside a metal tube 2. The filler material 4 solidifies to integrate the optical fiber core wire 3 and the metal tube 2 together. The inner periphery of the metal tube 2 is formed to have a rough surface.</p> |
