PROBLEM TO BE SOLVED: To provide a soldering method which can quickly and stably carry out a soldering work irrespective of its simple structure. SOLUTION: A flame F of combustion gas is jetted into a through-hole portion 2 of a nozzle shape soldering iron member 1 having the through-hole 2 in order to fuse solder S by heating the iron member 1 from its inside with the flame F of the combustion gas existing inside the through-hole portion 2. In addition, the solder S is inserted into the through-hole portion 2 from a cut-out portion 4 provided on the tip end cylindrical portion 3 of the nozzle shape soldering iron member 1, and the solder S is fused by being brought into contact with the inside surface of the through-hole portion 2.
