| Zusammenfassung: | A separator with a heat-resistant insulation layer for an electric device includes a resin porous substrate and a heat-resistant insulation layer containing heat-resistant particles and a binder, the heat-resistant insulation layer being formed on at least one surface of the resin porous substrate. The heat-resistant particles contain alumina and a parameter X is 0.018 to 0.336. Parameter X is represented by X=Ca×Rzjis/D, wherein Cα is a ratio of the alumina, which occupies the heat-resistant particles, Rzjis is surface roughness of a surface of the heat-resistant insulation layer, the surface being opposite the resin porous substrate, and D is a thickness of the heat-resistant insulation layer. |
