Abstract
An electrode plate for a secondary battery with a nonaqueous electrolyte composed of a collector and an active material layer which is formed of at least an active material and a binder disposed on the collector, and said electrode plate is provided with a terminal mounting portion provided with a collector surface exposed to mount a terminal. In such electrode plate, the exposed collector surface of the terminal mounting portion has the same shape and size substantially as those of an area to which the terminal is actually mounted. The electrode plate may further be provided with an identification mark made by forming the active material layer in shape of pattern on an area at which the collector surface is exposed or by exposing the collector surface in the shape of pattern on an area at which the collector is covered with the active material layer.
