Abstract
A method for inspecting a battery, comprising: a first withstanding voltage determination step of housing an electrode laminate within a package and applying a first voltage between a positive electrode terminal and a negative electrode terminal to perform a first withstanding voltage determination in a state in which an electrolyte solution is not poured in the package; and a second withstanding voltage determination step of applying a second voltage which is higher than the first voltage between the positive electrode terminal or the negative electrode terminal and metallic layers of pair of laminate films to perform a second withstanding voltage determination in the state in which the electrolyte solution is not poured in the package.
