Abrégé

Provided are a vertical fuse and a vertical fuse device capable of solving problems from which a conventional vertical fuse and a conventional vertical fuse device have suffered. A fuse holder 7 which is an insulating member used in a vertical fuse device 10, is a molded resin component that is integrally molded from a resin having electric insulating properties. The fuse holder 7 at least comprises: a first insulating part 71 which is positioned between a second portion 34B of a first lead terminal 34 and a second cap-like electrode 33 and which provides electrical insulation between the second portion 34B and the second cap-like electrode 33; a second insulating part 72 which is positioned between the second cap-like electrode 33 and a second portion 35B of a second lead terminal 35 and which maintains the dimensions of a gap between the second portion 35B of the second lead terminal 35 and the second cap-like electrode 33; and an electrode fitting part 73 which is positioned between the first insulating part 71 and the second insulating part 72 and to which the second cap-like electrode 33 is fitted.

Abrégé

Provided is a fuse that not only can be made smaller than in the prior art, but is also capable of causing an electric discharge to be initiated from a fuse part located in the central region of a fuse element. Four fuse parts (71A-71D) and five non-fuse parts (73A-73E) are arranged alternately side by side along a virtual central line (L1). The four fuse parts (71A-71D) are each formed so as to extend along a virtual crossing line (L2) that intersects the virtual central line (L1) of the metal plate. Of the four fuse parts (71A-71D), the two fuse parts (71B, 71C) that are positioned in the central region have lengths along the virtual crossing line (L2) that are longer than the lengths of the other two fuse parts (71A, 71D) along the virtual crossing line (L2).
