Abstract

A method of fabricating a hermetic terminal includes: joining and firing wherein a bar-shaped member to be a lead is inserted into a ring, and they are fired to form a hermetic terminal intermediate having the bar-shaped member fixed in the ring; flattening wherein an end part of the bar-shaped member to be the inner lead portion of the lead is flattened to form a stair portion; and shaping wherein an end part of the stair portion is cut to shape the stair portion into a predetermined shape, wherein in the joining and firing step, a solid round bar longer than the lead is used as the bar-shaped member, and one end side of the bar-shaped member to be the inner lead portion is inserted into the ring so that the one end side is longer than the inner lead portion in the hermetic terminal as a completed product.
