ABSTRACT:
A current collector sheet for an electrode of an electrochemical device has a conductive area and an insulating area on the surface thereof. Examples of the current collector sheet includes: a current collector sheet including an insulating sheet, wherein the conductive area has a conductive layer formed on the surface of the insulating sheet, and the insulating area has an exposed portion of the insulating sheet; a current collector sheet including a conductive sheet, wherein the insulating area has an insulating layer formed on the surface of the conductive sheet, and the conductive area has an exposed portion of the conductive sheet; and a current collector sheet including a conductive sheet portion and an insulating sheet portion positioned flush with each other, wherein the conductive area has a surface of the conductive sheet portion, and the insulating area has a surface of the insulating sheet portion.
