Provided is a sealed contact device having a small number of components and high productivity. In the sealed contact device, therefore, a ring-shaped flange portion 32a extending laterally from a lower opening edge part of a metallic case 32 is welded and integrated with an upper surface of a plate-shaped yoke 37 to form an internal space and a stationary contact 33a and a moving contact 48a are opposed to each other in the internal space so as to enable approach/separation. In particular, a ring-shaped projection 32c provided along a lower surface of the ring-shaped flange portion 32a is integrated with the upper surface of the plate-shaped yoke 37 by resistance welding. |
