Abstract
A method for testing an all solid state battery with which the presence of short circuit or the presence of defect causing short circuit can be detected with high accuracy by a method in which a voltage is applied to a battery and the current value thereof is measured. The method includes the steps of: a resistance increasing step of increasing resistance of an all solid state battery to 3.2*105 Ω·cm2 or more; a voltage applying step of applying voltage to an all solid state battery of which the resistance is increased; and a judging step of judging acceptability of the all solid state battery based on a current value measured in the voltage applying step.
