To provide a resistance-welding device capable of stabilizing a welding quality.SOLUTION: A resistance-welding device 1 welds by flowing an electric current by pressurizing in the mutually approaching direction by allowing a bracket (a first member) 2 and an outer tube (a second member) 3 to abut on each other. The resistance-welding device 1 comprises a first electrode 10, a second electrode 20 and a first holding member 30. The first electrode 10 abuts on the bracket 2 while being energized. The second electrode 20 is oppositely arranged to the first electrode 10, and abuts on the outer tube 3. The first holding member 30 comprises a first V-shaped surface (a first holding surface) 34 for holding the bracket 2, and presses the bracket 2 in the outer tube 3 direction by this first V-shaped surface 34. The first holding member 30 has electrical insulation properties to the first electrode 10. The first holding member 30 slidably inserts the first electrode 10 into an insertion hole 33 opening on the first V-shaped surface 34 side.SELECTED DRAWING: Figure 1 【課題】溶接品質の安定化を図ることができる抵抗溶接装置を提供する。【解決手段】抵抗溶接装置１は、ブラケット（第１部材）２とアウターチューブ（第２部材）３とを当接させて互いに接近する方向に加圧し、電流を流して溶接する。抵抗溶接装置１は、第１電極１０、第２電極２０、及び第１保持部材３０を備えている。第１電極１０は、付勢されつつブラケット２に当接する。第２電極２０は、第１電極１０に対向して配され、アウターチューブ３に当接する。第１保持部材３０は、ブラケット２を保持する第１Ｖ字状面（第１保持面）３４を有し、この第１Ｖ字状面３４によりブラケット２をアウターチューブ３の方向に押圧する。また、第１保持部材３０は、第１電極１０に対する電気絶縁性を有している。そして、第１保持部材３０は、第１Ｖ字状面３４側に開口する挿通孔３３に第１電極１０を摺動自在に挿通している。【選択図】図１
