PROTECTION ELEMENT

Abstract: this protection element is equipped with: a fuse element which conducts electricity in a first direction from a first end section toward a second end section; a shield member; and a case, the interior of which is provided with a storage section for storing the fuse element and the shield member. the shield member has a plate-shaped part which is positioned in a manner such that a first surface thereof faces the fuse element and a second surface thereof contacts a rotating shaft which extends in a second direction which intersects the first direction. the surface area of the plate-shaped part when viewed from the fuse element is configured in a manner such that a first surface area and a second surface area, which are obtained by dividing at the contact location between the plate-shaped part and the rotating shaft, differ from one another.
