PROBLEM TO BE SOLVED: To provide a soldering method by which delaying factor of a time needed to change a substantial jet wave height can be extremely minimized. SOLUTION: The jet direction of the jet wave is formed variable and the jet wave height is adjusted by varying the direction while matching to carrying of a printed circuit board 11. Further, in the case of carrying the printed circuit board 11 at an elevation angle, the jet direction of the jet wave is formed so as to be shiftable in the horizontal direction to adjust the relative jet wave height with the printed circuit board 11. In such a way, the delay of time is removed and the adjustment of the jet wave height can be performed with good timing.
