Abstract
An electrode plate for a secondary battery is provided for reducing adverse influences caused by paste of an insulating sheet in an electrode body and a battery specification. Active material layers 22a to 22d and 22a′ to 22d′ are formed on at least one surface of an electrode sheet 20 over a wider range than a predetermined width of an electrode and over a predetermined length. An insulating sheet 13a is made to adhere to a possible short-circuit portion of the electrode sheet 20 which portion is opposed to another electrode. The electrode sheet 20 and an insulating member are simultaneously cut to form an electrode plate having a predetermined shape, wherein the insulating member has a low-temperature thermoplastic paste material applied on one side thereof, and is made to adhere to the electrode sheet 20 through heat adhesion.
