PROBLEM TO BE SOLVED: To provide a contact device that prevents an increase in temperatures of fixed contacts and a movable contactor due to generated arc, without increasing contact resistance.SOLUTION: A contact device includes: a pair of fixed terminals 1 that have respective fixed contacts 10; a movable contactor 2 that is moved into and out of contact with the fixed contacts 10; and a sealing container 4 that seals the fixed contacts 10 and the movable contactor 2. A heat dissipation structure composed of projections and depressions is provided by forming a plurality of protrusions 1A and 2B in the fixed terminals 1 and the movable contactor 2, respectively. The heat dissipation structure is provided in a region other than contact surfaces between the respective fixed contacts 10 and the movable contact 2. |
