To prevent the power consumption from being increased, and to prevent the thrust to be applied to a brazing filler metal from being reduced in a brazing device of electro-magnetic induction pump type.
Electro-magnetic induction pumps 46, 47 are provided along the work carry-in side and the work carry-out side of a tank body 33 to store a brazing filler metal 32. In the electro-magnetic induction pumps 46, 47, a primary core 52 in which an induction coil 51 is wound is arranged outside the tank body 33, and a secondary core 54 is arranged inside the tank 33 through a clearance for elevation of the brazing filler metal. In the primary core 52, a plurality of split cores 52E are arranged in close contact manner on the outer surface of the tank body 33. A primary core pressing mechanism 81 to press the primary core 52 to the outer surface of the tank body 33 by a spring member 85 is provided on the primary core 52. A secondary core pressing mechanism 86 to press the secondary core 54 in the direction in which the clearance 53 for elevation of the brazing filler metal is minimized is provided on the secondary core 54.
