Claim 21:
22. The internal heat exchanger according to claim 21, wherein
a positional relationship between the distal end of the inner pipe, the flange portion, the inner pipe side sealing member, the distal end of the outer pipe, and the outer pipe side sealing member, and the inner pipe insertion portion, the outer pipe insertion portion, and the contact portion of the connector define a structure, in which
a distance of the distal end of the inner pipe and the flange portion is longer than a sum of a distance of the inner pipe O-ring holding portion among the inner pipe insertion portion and a diameter of the inner pipe side sealing member, and wherein
