PROBLEM TO BE SOLVED: To provide a contact structure in which reliability of a product is improved by greatly reducing an occurrence probability of a conduction failure between a fixed and a movable contacts due to adhesion of a foreign matter such as dust. SOLUTION: A fixed contact 6 and a movable contact 7 provided in a fixed contactor 2 and a movable contactor 3 of a current breaking part are made to be a disk contact of "gable shape" of its surface consisting of two taper faces 6c, 7c and ridge line portions 6b, 7b at the center, and by arranging the ridge line portions 6b, 7b in the direction to cross each other, the fixed contact 6 and the movable contact 7 are adhered by brazing to the fixed contactor 2 and the movable contactor 3.
