PROBLEM TO BE SOLVED: To provide a water-proof electrode structure that is simple and facilitates work.SOLUTION: An electrode structure includes an opening part formed on a housing, a cylindrical electrode housing part formed from the opening part to the interior of the housing and having a larger inner diameter than the opening part, an electrode module inserted into the electrode housing part, and an opposite terminal electrically connected to the electrode module. The electrode module has an electrode part which is an elastic body with electric conductivity and fitted in the opening part, and a body part which has a larger diameter than the electrode part and is longer than the electrode housing part, and also has a sealing ring part larger than the inner diameter of the electrode housing part in the middle of the body part. Further, the opposite terminal is provided where the opposite terminal abuts against a rear end part of the electrode module. |
