PROBLEM TO BE SOLVED: To provide a sealed contact device, enabling simplification of its manufacturing process and reduction of its manufacturing cost, and having full bonding strength and air tightness. SOLUTION: Members 11, 13 for contacts are composed of columnar shaft portions 19, 21, stretched portions 23, 25 annularly and radially stretching out at the back ends of the shaft portions 19, 21, and disc-like stationary side contacts 27, 29 bonded to the tips of the shaft portions 19, 21. Intermediate members 31, 33 are externally fitted to the periphery parts on the lower surface side of the stretched portions 23, 25. Ceramic side-projecting portions 35, 37 are formed on the upper surface of the top part 9 of a sealed vessel 7. Accordingly, the intermediate members 31, 33 are bonded and gas-sealed, by a bonding structure, comprising a metallized layer, an alloy layer, and a brazing material layer on the upper surfaces of the ceramic-side projecting portions 35, 37.
