Zusammenfassung:	[Object]To provide a current collector for electrical storage device which allows an electrical storage device to attain a low resistance.[Solution]A current collector for electrical storage device includes a sheet-shaped conductive substrate and a coating layer disposed on one or both sides of the conductive substrate. The coating layer includes a powdery carbon material, acid-modified polyvinylidene fluoride and polyvinylpyrrolidone. The content of the polyvinylpyrrolidone is 0.099 to 5.0 mass%. The content of the powdery carbon material in the coating layer is 15.0 to 45.0 mass%.
