PROBLEM TO BE SOLVED: To provide a nozzle for supplying brazing filler metal with which a prescribed amount of the brazing filler is supplied onto a heated substrate by bringing the tip end part of the brazing filler metal into contact with the heated substrate and melting the brazing filler metal. SOLUTION: A partition wall bush 6 is arranged in a hollow part 5 of a nozzle main body 4, and an inflow port 7 and an exhaust port 8 for cooling gas are arranged in the nozzle main body 4, and a pipe member 10 is fitted to the lower part of the nozzle main body 4 and a guide pipe 10 is fixed to the pipe member 9. On the nozzle main body 4, a positioning member 12 and a nozzle guide 13 supports the guide pipe 10 concentrically with the partition wall bush 6. The cooling gas supplied from the inflow port 7 is exhausted from the exhaust port 8 through a gap formed between the circumferential surface of the pipe part 6b of the partition wall bush 6 and the inner peripheral surface of the pipe member 9 after passing through a gap formed between the inner peripheral surface of the pipe part 6b and the circumferential surface of the guide pipe 10 then returning at the tip end part of the pipe part 6b.
