Abstract
Provided is an electrode material constituting a movable electrode 50 of a thermal fuse 1, wherein the electrode material has a clad structure where a base layer including Cu or a Cu alloy is joined to a contact point layer made of a Ag—CuO based oxide-dispersion-strengthened alloy. The present invention is an electrode material that is suitable for a movable electrode of a thermal fuse and can solve the problem of the failure of contact with the case in association with long-term use. In this electrode material, it is preferable that a contact layer including Ag be joined to a back surface of the base layer in order to improve resistance to contact with a case 10.
