  • Protection element
    Patent number: 10050431
    Abstract: The present invention provides a protection device which includes a laminar element 16 which is formed of an insulation resin and has at least one throughhole; electrically conductive metal thin layers 22 and 28 which are positioned on each of main surfaces of the laminar element, and a fuse layer 40 which is positioned on a side surface defining said at least one throughhole and electrically connects the electrically conductive metal thin layers. The fuse layer includes a first metal layer 41 consisting of a metal having a higher melting point and a second metal layer 42 consisting of a metal having a lower melting point. The protection device of the present invention allows a larger amount of a current to flow therethrough and can provide a protection from an excessive current.
