摘要： A method for testing a precursor of a secondary cell with high reliability and high efficiency to judge the precursor to be acceptable or defective. The current flowing when a test voltage is applied between a pair of electrodes is measured before an electrolyte is placed between the electrodes. If a current the current value of which exceeds a predetermined reference current value (13) is detected during the time from the start of application of a voltage to a normal secondary cell precursor until the current becomes constant, the precursor is determined to be defective.
