。[Scope of Claim for Utility Model Registration] (1) Optical fiber in which a required number of optical fiber cores are housed in a spacer with a groove capable of storing them in a spiral shape, and a heat insulating layer made of an inorganic substance and a protective layer of plastic are sequentially applied thereon. A cable core and a required number of power wire cores each having an insulator mainly made of polyolefin on the conductor are twisted together with an inclusion, and on the outside are a plastic protective layer, a heat insulating layer made of inorganic fiber, and a mesh-like structure. An optical/power composite fire-resistant cable characterized by sequentially providing layers of carbonized tape or cloth coated with foamable fire-retardant paint. (2) The optical/power composite fire-resistant cable according to claim 1, wherein the spacer, insulator, inclusion, and protective layer are made of non-halogen materials. (3) The optical/power composite fire-resistant cable according to claim 1, wherein the protective layer is composed of 100 parts by weight of polyolefin and 50 to 200 parts by weight of aluminum hydroxide.
