摘要:
A method for producing an airtight terminal having an annular stem, a lead passing through the stem and formed of a conductive material, and a filler for fixing the lead in the stem includes (1) a lead contour formation step of disposing a base and a lead formation portion on a plate- or strip-shaped conductive material and forming a contour of the lead on the lead formation portion with at least one end of the lead connected to the base, (2) a filler shaping and sintering step of filling the lead having a contour with the filler in a predetermined position and shaping and sintering the filler, (3) a stem mounting step of mounting the stem to a perimeter of the sintered filler, (4) a firing step of heating, melting, and cooling the sintered filler in the stem and bringing the lead into close contact with the stem to fix the lead to the stem through the filler, (5) a metal film formation step of forming a metal film on a surface of the lead, and (6) a cutting step of separating the one end of the lead from the base.
