Abstract
A current interruption device includes a first conductive member, a second conductive member, a first deformable member, a second deformable member, and a first seal member. The second conductive member is disposed at a position opposed to the first conductive member. A center portion of the first deformable member is fixed to the second conductive member. The second deformable member is disposed on a side opposite to the first deformable member relative to the second conductive member. The first seal member is disposed between the first conductive member and the second conductive member. A second seal member is disposed between the first conductive member and the casing. A gas permeability between the casing and the first conductive member is equal to or less than a gas permeability between the first conductive member and the second conductive member.
