PROBLEM TO BE SOLVED: To secure flexibility of a piping part and rigidity of a pipe body support member without using a special component.SOLUTION: A header member 10 has a piping part 20 which is formed of a resin material and composes a main piping 102 of a coupling type header 100, and the tubular pipe body support member 32 which composes a part of a branch pipe 30 diverging from the piping part 20 and is formed of a resin material harder than the piping part 20 and simultaneously is integrally formed with the piping part 20 by insert molding and supports a resin pipe 104 from inside by being inserted into the resin pipe 104 connected to the branch pipe 30 and on which an O-ring 48 stopping water between an outer peripheral part and the resin pipe 104 by coming into close contact with inner peripheral surface of the resin pipe 104 is disposed on an outer peripheral part. |
