PROBLEM TO BE SOLVED: To provide a brazing device capable of adjusting the temperature of flame even when using a gas burner. SOLUTION: The brazing device 1 using a gas burner B for performing the brazing with flame with which inflammable gas and gaseous oxygen are burned comprises: a temperature detection means 2 capable of detecting the temperature of flame in a vicinity of a part to be brazed; and a gas flow adjusting means 3 which is connected to the temperature detection means 2 to receive the temperature detected by the temperature detection means 2, and capable of controlling the flow of inflammable gas and gaseous oxygen according to the temperature detected by the temperature detection means 2. The gas flow rate adjusting means 3 controls the flow rate of inflammable gas and gaseous oxygen so that the temperature detected by the temperature detection means 2 is equal to or higher than the brazing filler metal melting temperature and equal to or lower than the boiling point of zinc of a galvanized steel sheet.
