PROBLEM TO BE SOLVED: To provide a flexible oil-proof hose formed by winding a signal wire such as an electric cable on a hose, transmitting a signal, and reducing abrasion, damage or the like of the signal wire. SOLUTION: A liquid injection hose 11 is composed of the multilayer hose 12 composed of a long cylindrical body, the electric cable 20 as the signal wire, a protective tape 21, a metallic outer wire 22 or the like. The electric cable 20 is wound on an outer peripheral side of an envelope 19 of the hose 12 with a comparatively large spiral pitch, and the electric cable 20 is adhered and fixed to the hose 12 by the protective tape 21. The metallic outer wire 22 is wound on the protective tape 21 at an outer peripheral side of the hose 12 with a small spiral pitch. The spiral direction of the electric cable 20 is opposite to the spiral direction of the outer wire 22, thus a problem on disordering or the like caused by loosening of the electric cable 20 can be prevented.
