PROBLEM TO BE SOLVED: To provide a breaker which obtains a stable resistance value and good temperature characteristics during conduction by reducing distortion of a case while achieving miniaturization.SOLUTION: A movable piece 4 includes: a first elastic part 43 which generates elastic force for pressing a movable contact 3 against a fixed contact 21; and a second elastic part 42a which abuts on a case 7 and generates elastic force for holding the attitude of the movable piece 4 with respect to the case 7. |
