Abstract

An electrode probe is brought into contact with a measurement part on an outer surface of at least one of the positive electrode and the negative electrode of a sheet type cell, and quantity of electricity is measured at the measurement part, so as to evaluate the sheet type cell. The electrode probe may be connected to a voltage meter and to a charge source or a discharge source, and the evaluation made by detecting a charge characteristic that changes the cell from a non-charged state to a fully charged state, a discharge characteristic that changes the cell from a fully charged state to the non-charged state, or a measurement voltage of the voltage meter when the cell is in the fully charged state.
