[Problems] Providing a compact breaker which enables to reduce contact resistance and to miniaturization much more by maintaining contact positions of a stationary contact and a movable contact appropriately. [Means to solve the Problems] In a breaker comprising a stationary piece 2, a movable piece 3, a bimetal 4 and a case 6, the movable piece 3 has a second elastic portion 35 having an elastic coefficient lower than that of a first elastic portion 34, and is fixed on the case 6 at a fixation portion 33 between the first elastic portion 34 and the second elastic portion 35. |
