Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchanger enabling to securely apply flux to a brazing part so as to provide stable brazing when a pin and bracket for forming a mounting part is integrally brazed on a main body side by using a flux brazing method. SOLUTION: The heat exchanger includes a bar shaped pin 131, and the bracket 132 formed of a plane material having a hole 132a for inserting the pin 131 with brazing material clad on a surface, and is formed by integrally brazing after the pin 131 is inserted so as to pass through the hole 132a of the bracket 132, and the bracket 132 is temporarily fixed to the header tank 110 or the core part 120. The brazing uses the flux. A groove 132b for passing in an insertion direction of the pin 131 is provided on a part where the pin 131 and the hole 132a abut each other, and the flux applied to the pin 131 and the bracket 132 is wet flux.
