PROBLEM TO BE SOLVED: To provide a fire-fighting hose which can improve the extensibility that the hose is easily extended from a storage condition and the so-called expandability that the hose is expanded straight, and improve the so-called flowability, i.e., the floodable speed of water in the hose when water is passed through the hose. SOLUTION: A lining layer 2 consisting of rubber or synthetic resin is fitted to an inner surface of a jacket 1 in which warps 1a and wefts 1b are formed in a cylinder, and an expansion promotive part 5 to apply the weight in the expanding direction when the hose is expanded is provided on a handle part 4a or its reverse side 4b between edge parts 3 which are both ends in the condition where the hose is folded flat.
