PROBLEM TO BE SOLVED: To provide a hose having such an inner tube structure that can prevent the hose from being deteriorated by chlorine present in water and hot water and also prevent it from odorizing and being colored. SOLUTION: This hose for water supply/hot water supply comprises an inner layer tube 1 and a reinforcement layer 2. The inner layer tube comprises an inner layer formed of a copolymer fluoroplastic having tetrafluoroethylene, vinylidene fluoride, and hexa fluoropropyrene and an outer layer 1B formed of a polyorefine elastomer or a styrene elastomer. An intermediate resin layer 1C formed by mixing an ethylene copolymerplastic containing glycizil metacrylate in polyethylene or polypropyrene is disposed between the inner layer and the outer layer.
