A cooling inner sheath (2) is provided on the outer periphery of the sheath (2) via a spiral spacer (U), and an external cooling sheath (2) is similarly provided on the outer periphery of the inner sheath (2). The space formed by the spiral partition wall (1) and the cooling sheath (4) becomes a cooling water passage, and the cooling water flows along the partition wall (2) in the direction of the arrow in the figure.

。In the specific examples shown in FIGS. 1 and 2 above, the cooling sheath (41 (10) and the gap (121) are made of a material with excellent heat resistance and water resistance, such as Teflon. (Although pure water is preferable as the cooling water, for example, when used as an in-body treatment device, it is more preferable to use physiological saline.) As described above, according to the optical fiber cable of the present invention,
A cooling water passage is provided outside the infrared light transmission path and the sheath temperature is lowered by flowing cooling water, so temperature rise due to leakage light is suppressed, and it is safe to handle and there is no risk of burns.
