<p>PROBLEM TO BE SOLVED: To provide an electrode holder capable of stably maintaining a good sealability and improving durability even when installed in a container under a high temperature and a high pressure.SOLUTION: An electrode holder 1 comprises: a metallic cylindrical container fitting member 10 fixed to a container 2; an electrode shaft 20; and an insulation member 30 provided by insulating the cylindrical container fitting member 10 and the electrode shaft 20 in a gap therebetween. The insulation member 30 has: a water repellent cover part 35 exposed into the container 2 and coating the electrode shaft 20 for protection; and a load part 31 not exposed into the container 2 and including a portion on which a load received from the electrode shaft 20 by a pressure within the container concentrates. The water repellent cover part 35 is formed of a first insulation material which is resin with water repellency and sealability. The load part 31 is formed of a second insulation material with higher intensity than the first insulation material.</p> |
