Abstract: This breaker device includes: a holder including a first internal space and a second internal space located below the first internal space; a conductor located between the first internal space and the second internal space and held on the holder; a pusher disposed in the first internal space; and a drive source that moves the pusher from the first internal space toward the second internal space. The conductor includes: a first embedded portion held on the holder; a second embedded portion held on the holder; and a partition portion disposed between the first embedded portion and the second embedded portion. The pusher is located above the partition portion. The first embedded portion includes: a thin portion connected to the partition portion; and a thick portion located opposite the partition portion across the thin portion. The thickness of the thick portion in the up-down direction is greater than the thickness of the thin portion in the up-down direction.
