PROBLEM TO BE SOLVED: To cope with increase of a length while applying a connection header of two-kind member structure, in a heat exchanger having a structure in which flat tubes adjacent to each other in a tube row direction, are communicated through the connection header.SOLUTION: A connection header (74) is constituted by joining a plurality of second members (90, 90a-90g) forming a plurality of connection passages (75) to communicate longitudinal one end portions of flat tubes (61) adjacent to each other in a tube row direction by being joined to a first member (80), to the first member (80) provided with a plurality of through holes (82) through which the longitudinal one end portions of the plurality of flat tubes (61) penetrate.SELECTED DRAWING: Figure 8 |
