INSPECTION METHOD OF ELECTRODE PLATE

摘要

PROBLEM TO BE SOLVED: To provide an inspection method of an electrode plate capable of enhancing both the workability and inspection accuracy of inspection.

SOLUTION: By using a press die 5 provided movably in the direction approaching to and receding from an electrode material layer 9, a load P of a first predetermined value P1' is made to act in a direction perpendicular to the electrode material layer 9. The load P is increased from the first predetermined value P1'. Acceptability of an electrode plate 7 is inspected based on the travel S2-S1' of the press die 5 when the load P by the press die 5 increases from the first predetermined value P1' to a second predetermined value P2.
