PROBLEM TO BE SOLVED: To provide a tube for a heat exchanger for more effectively and rigidly brazing opposed sites of a top of a bead and an inside of the tube. SOLUTION: In the tube for a heat exchanger for brazing a top of a bead 21 provided on a brazing sheet B for constituting the tube to an opposed site of an inside of a tube component 20 by providing the bead 21 and the method for manufacturing the tube, a thickness t' of the component 20 before brazing is set to larger size than a predetermined thickness (t). At the time of brazing, the component 20 is compressed in its thickness direction. Thus, the top of the bead 21 is crushed or lodged in the opposed site of the inside of the component 20. |
