To provide an end fastening structure of a hose fitted with a bellow type metal pipe capable of eliminating a stress concentration in the welded part between the bellow type metal pipe and an insert pipe when the end of the hose is fastened and precluding the risk of destruction in that part.

When the end of the hose 10 is to be fastened, the insert pipe 14 made of metal is fitted in the bellow type metal pipe 22 for a specified length from its forefront, and in the fit-in part, the insert pipe 14 and the bellow type metal pipe 22 are overlapped in the radial direction, and in the overlapped condition, the forefront of the metal pipe 22 is welded to the insert pipe 14.
