PURPOSE: A multilayered hose is provided to be used as an electric wire by inserting an electric wire between a heat insulation layer and a second reinforcement layer. CONSTITUTION: A multilayered hose comprises a water pipe(10), first and second reinforcement layers(20, 40), a heat insulation layer(30), and an outer layer(50). The water pipe is formed into hollow shape and forms a water channel. The first reinforcement layer covers the water channel. The heat insulation layer covers the first reinforcement layer. The second reinforcement layer covers the heat insulation layer. The outer layer covers the second reinforcement layer. Two electric wire(60) covered with a thermal insulating materials are inserted between the heat insulation layer and the second reinforcement layer.
