PROBLEM TO BE SOLVED: To provide a soldering method requiring no flux. SOLUTION: Solder 6 is arranged on the soldering face 2a of one of the two objects 2, 4 to be soldered. While a free radical gas is supplied to this soldering face 2a and the soldering face 4a of the other object 4, the two objects 2, 4 are heated to a temperature at which the solder 6 is melted and are then cooled. The soldering face 2a on which the solder 6 is melted is superposed on the soldering face 4a of the other object 4, heated at the melting temperature of the solder 6, and subsequently cooled.
