    • A substantially ring-shaped seat section (8) protrudes from an inner circumference wall in a through hole (4) of a container attaching section (6) made of a metal. On an outer circumference of an electrode shaft (3) held in the through hole (4) through an insulator (5) made of a synthetic resin, locking protrusions (13, 14), which have a diameter larger than a hole diameter of the seat section (8), are provided at a distance from the seat section (8), on at least inner side or outer side of the seat section (8) in a shaft direction of the electrode shaft (3). Thus, for instance, when the inside of the metal container (2) is at a high temperature, the insulator (5) is destroyed and the electrode shaft (3) is to jump out from the container attaching section (6) to the outside or the inside of the metal container (2), the locking protrusions (13, 14) lock the seat section (8) and prevent the electrode shaft (3) from jumping out. Furthermore, since a space provided between the electrode shaft (3) and the container attaching section (6) due to the destruction of the insulator (5) is covered by having the locking protrusions (13, 14) lock the seat section (8), leakage of a liquid in the metal container (2) can be suppressed to minimum even the insulator (5) is destroyed.
