Provided is a brazing apparatus that uniformly raises the temperature of workpieces by means of a relatively simple structure, and is capable of high-speed brazing. This brazing apparatus (SB) is sequentially provided with an anterior chamber (13) in which air is substituted with an inert gas, and brazing chambers (14, 16) in which heat exchangers (workpieces) (W) are heated. Aluminum members constituting the heat exchangers (workpieces) (W) are brazed inside the brazing chambers (14, 16). The brazing apparatus (SB) is provided with a near-infrared irradiation device (an auxiliary heating means) (31) that is disposed in the anterior chamber (13), and heats a region (a header section (1)) of each heat exchanger (workpiece) (W) which rises in temperature slowly. |
