PROBLEM TO BE SOLVED: To enhance working efficiency and suppress an increase in the cost without oxidizing a brazed part and the periphery thereof when joining a base material as a metallic member having the shape such as a tubular shape with a hollow inside such as a pipe with a base material as another metallic member. SOLUTION: A brazing device includes: a fixing means for fixing one base material; a positioning means constituted of a pin for discharging an inert gas from a hole formed in one end, and a shaft which presses one base material against the other base material, allows the inert gas discharged from the pin to flow into the hole provided to one end and to flow out the inert gas from a side surface part via an air duct; a rectifying collar which is provided to the side surface part of the shaft, rectifies the inert gas flowing out from the side surface part along the surface of the other base material, and joins one base material with the other base material with a brazing filler metal; a closing means for forming the periphery of the brazed part in a substantially-closed space; and a heating means for heating the brazed part.
