PROBLEM TO BE SOLVED: To equalize brazing portions formed by an automatic brazing device configured to convey joining members by a belt conveyor at a fixed rate, since, in such a device, the distance between a burner and each joining member varies due to the interval of guides being larger than the width of the joining members and can cause a change in heat input for each joining member.SOLUTION: The automatic brazing device includes: a placement table for fixing and placing joining members; a first burner unit including a plurality of burners disposed in an annular shape, with the rotating surfaces of the burners being disposed vertically; and a second burner unit including a plurality of burners disposed in an annular shape, with the rotating surfaces of the burners being disposed vertically. The first burner unit and the second burner unit are opposed to each other leaving a space, with the respective burners facing the counter side, and the burners draw a flattened circle-like track.
