Discloses is a flexible water pipe in which a pipe body has high rigidity and obtains excellent bending and expansion performances. A flexible water pipe includes a pipe body (10) in which ring-shpae unit bodies (10a) made of hard material being continuously connected to form a water passage therein. Each of the ring unit bodies (10a) includes an inner tube body (11) formed at one side thereof as a cylindrical body having a small pipe diameter at one side thereof. An outward protrusion (11a) is formed at an outer periphery of the inner tube body (11). An outer tube body (12) is formed at another side thereof as a cylindrical body having an increased pipe diameter thereof so that the inner tube body (11) is flowingly fitted into the the outer tube body (12) to overlap with an inner side of the outer tube body (12). An inward protrusion (12a) is formed at an inner periphery of the outer tube body (12). The inner tube body (11) and the insertion portion (12) causing adjacent ring-shaped unit bodies (10a) to be bent and expanded.
