Abstract
A water pipe includes a pipe main body made of a synthetic resin and an annular metal inner piece inserted into an end of the pipe main body. The inner piece has its diameter increased from the inside of the pipe main body so as to increase the diameter of at least a part of that portion of the pipe main body which corresponds to the inner piece. The inner diameter of the inner piece the diameter of which has been increased is almost the same as that of a portion of the pipe main body which is not enlarged by the inner piece.
