Abstract: A protection element includes: a fuse element configured to be energized in a first direction, which is a direction from a first end portion of the fuse element to a second end portion of the fuse element; a shielding member including a plate-shaped part, configured to rotate around a rotation axis extending in a second direction orthogonal to the first direction, wherein the plate-shaped part viewed from the fuse element is divided to a first portion and a second portion at a contact position between the plate-shaped part and the rotation axis, and an area of the first portion and an area of the second portion are different from each other; and a case having therein a housing portion. Pressure elevation in the housing portion due to an arc discharge causes the shielding member to rotate around the rotation axis and the shielding member divides the housing portion.

Abstract: A fuse element capable of surface-mounting and capable of increased ratings while maintaining high-speed blowout property; and a fuse device using the same. A fuse element blown by self-generated heat caused when a rate-exceeding current flows therethrough constitutes a current path of a fuse device and has a low melting point metal layer and a high melting point metal layer laminated onto the low melting point metal layer; when the current flows therethrough, the low melting point metal layer erodes the high melting point metal layer and blowout occurs.
