PROBLEM TO BE SOLVED: To provide a brazing device capable of achieving acceleration of temperature rise rate of a workpiece.SOLUTION: A brazing device 1A has a sealed body 2 and a heating element 20. The sealed body 2 has a cylindrical body 3 in which at least one end side in an axial direction is opened and at least one lid body 10 occluding the opening 3a of the cylindrical body 3 in an airtight state. The brazing device 1A melts a brazing material 32 of a workpiece 30 by transferring heat of the heating element 20 to the workpiece 30 via an outer peripheral wall 4 in a state that an inner part 2a of the sealed body 2 is in an inert gas atmosphere, the heating element 20 contacts to an outer face 4b of the outer peripheral wall 4 of the cylindrical body 3, and an inner face 4a of the outer peripheral wall 4 contacts to the workpiece 30. The heating element 20 is pressed against the workpiece 30 relatively via the outer peripheral wall 4 of the cylindrical body 3 when melting the brazing material 32. The outer peripheral wall 4 of the cylindrical body 3 has a thickness which can elastically deforms following to press operation of the heating element 20 to the workpiece 30. 【課題】ワークの昇温速度の高速化を図ることができるろう付け装置を提供する。【解決手段】ろう付け装置1Aは密封体２と発熱体20を具備する。密封体２は、軸方向の少なくとも一端側が開口した筒状体３と、筒状体３の開口3aを気密に閉塞する少なくとも一つの蓋体10とを備える。そしてろう付け装置1Aは、密封体２の内部2aが不活性ガス雰囲気にされ且つ発熱体20が筒状体３の外周壁４の外面4bに接触するとともに外周壁４の内面4aがワーク30に接触した状態にして、発熱体20の熱が発熱体20から外周壁４を介してワーク30に伝導伝熱により伝えられることにより、ワーク30のろう材32を溶融するものとなされている。発熱体20は、ろう材32を溶融する際に筒状体３の外周壁４を介してワーク30に相対的に押し付けられるものである。筒状体３の外周壁４は、発熱体20のワーク30への押付け動作に追従して弾性変形可能な肉厚を有している。【選択図】図１
