A sensing cable comprising:
- a first optical fiber;
- a second optical fiber that extends along the first optical fiber and that is spaced from the first optical fiber;
- and
- a transmitting material including an intervention portion present between the first optical fiber and the second optical fiber, the transmitting material being configured to transmit light from the first optical fiber to the second optical fiber through the intervention portion, wherein
- on a cross-section intersecting a longitudinal direction of the first optical fiber at a position at which the intervention portion is arranged, an outer periphery of the first optical fiber includes a first section and a second section, the first section being in contact with the intervention portion and being optically connected to the intervention portion, the second section being separated from the intervention portion.
