    摘要： There is provided an electromagnetic contactor such that it is possible to improve productivity, and simplify a brazing jig, and furthermore, it is possible to control the flatness and warpage of a plate portion supporting fixed contacts. An electromagnetic contactor includes an arc extinguishing chamber (102) inside which is mounted a contact mechanism (1 11) having a pair of fixed contacts (111) and (112) and a movable contact (130) in contact with the pair of fixed contacts, wherein the arc extinguishing chamber (102) has a plate-like fixed contact support substrate (105) wherein metal foils are each formed at least around through holes (105) and (106) in which are fixed the pair of fixed contacts and on an outer circumferential peripheral edge of one surface by a metalizing process, is such that the pair of fixed contacts (111) and (112) and a metal cylindrical body (104) are brazed and joined to the metal foils of the fixed contact support insulating substrate (105), and an insulating cylindrical body (140) is disposed on the inner peripheral surface of the metal cylindrical body (104).
