Abstract: In a heating element (46) constituting a belt-shaped heater wire, the heater wire is configured such that short metal fibers are at least partially bonded to each other. A magnitude of a ratio of resistivity of the heating element (46) measured along a second direction orthogonal to a longitudinal direction of the heating element (46), to resistivity of the heating element (46) measured along a first direction which is the longitudinal direction of the heating element (46), is within a range of 0.9 to 1.1, and a magnitude of a ratio of the resistivity of the heating element (46) measured along the first direction, to resistivity of the heating element (46) measured along a third direction making an angle of 45° with respect to the first direction at a surface of the heating element (46), is not greater than 0.8 or not less than 1.2.

Abstract: To provide an electrode for an electricity storage device, which electrode employs a porous conductor having conductive nanostructures formed on its surface and makes it possible to provide a less expensive electricity storage device having a high discharge capacity and high charge/discharge cycle resistance.A porous conductor which is used as an electrode for an electricity storage device has a plurality of conductive nanostructures on a surface of the porous conductor.
