PROBLEM TO BE SOLVED: To sufficiently introduce molten solder even into a through-hole, while securing a jet width.SOLUTION: A jet nozzle 100 comprises a nozzle body part 30, and the nozzle body part 30 comprises an inflow port 601 and a discharge port 602 in a casing of a predetermined shape, and the molten solder 7 flowed in from the inflow port 601 is jetted to a printed circuit board 1 from the discharge port 602. A coarse flow part 10 is provided on one side in the longitudinal direction of the nozzle body part 30, and a coarse wave flow is formed of a part of the molten solder 7 flowed in from the inflow part 601. A flat flow part 20 is provided in the longitudinal direction on the side opposed to the coarse flow part 10, and a smooth flow is formed of the molten solder 7 jetted from the discharge port 602. A guide part 24 is provided in a predetermined position of the flat flow part 20, and guides the smooth flow above the coarse flow part 10. 【課題】噴流幅が確保できると共にスルーホールにも十分に溶融はんだを導入できるようにする。【解決手段】 噴流ノズル１００は、ノズル本体部３０を有し、ノズル本体部３０は所定の形状の筐体に流入口６０１及び排出口６０２を有して、流入口６０１から流入した溶融はんだ７を排出口６０２からプリント基板１へ噴流させる。ノズル本体部３０の長手方向の一方の側には荒流部１０が設けられて流入口６０１から流入した溶融はんだ７の一部で荒波流を形成する。荒流部１０に対峙する側の長手方向には平流部２０が設けられて排出口６０２から噴流した溶融はんだ７で平滑流を形成する。平流部２０の所定の位置には誘導部２４が設けられて平滑流を荒流部１０の上方へ誘導する。【選択図】 図２
