Abstract
A hermetic terminal according to the present disclosure includes a metal sleeve having a tubular shape, a ceramic substrate fixed to an inner peripheral surface of the metal sleeve and including a first through hole along an axial direction of the metal sleeve, an annular member including a second through hole located coaxially with the first through hole, and a conductive member having a columnar shape, inserted into the first through hole and the second through hole, and brazed to the ceramic substrate and the annular member. An inner peripheral surface of the annular member facing the conductive member includes a first region curved in a direction away from the conductive member.
