PROBLEM TO BE SOLVED: To connect a main pipe and a branch pipe by an arbitrary angle by only the combination with an existing piping member by providing a first joint member provided with a bent pipe receiving port having a certain curvature on its one end and a second joint member having the same curvature as the bent pipe receiving port on its one end and provided with a bent pipe part insertable to the bent pipe receiving port. SOLUTION: A pipe joint 1 has first/second joint members 2, 3 and the first joint member 2 has the bent pipe receiving port 21 of an arc angleα= about 25 deg. on its one end and a straight pipe shape straight pipe receiving port 22 on its other end. The second joint member 3 has the same curvature as the bent pipe receiving port 21 on its one end and the bent pipe part 31 of the arc angleβ= about 90 deg. insertable to the bent pipe receiving port 21 and the straight pipe part 32 for communicating therewith. On this bent pipe part 31, a cut line 33 is indicated in advance per 5 deg. arc angle toward the other end upto the 75 deg. position from the arc angle 15 deg. position from the end part of the straight pipe part 32 side. When a main pipe is connected to a branch pipe, the bent pipe part 31 is cut along the cut line 33 in response to a connection angle and its residual part is inserted to the bent pipe receiving port 21 of the first joint member 2 and adhered integrally.
