PROBLEM TO BE SOLVED: To obtain a proper solder junction between parts and a board. SOLUTION: Part conveyance arms 38 and 40 convey a part W to a solder junction position on a board B, and maintain the part W in a prescribed junction attitude at the solder junction position. A gas supply nozzle 47 is provided in a part retention hand 46 supported by the part conveyance arm 40 and supplied a heating gas for melting solder being coated to a junction part in advance, and a cooling gas for cooling the molten solder, thus fixing the relative position relationship between the retention position of the part W and a gas supply position, and maintaining the part W is maintained in the prescribed junction attitude on the board B.
