NOVELTY - The method involves laminating an electrode active material layer and a solid electrolyte layer (3) on single or both surfaces of a positive electrode electrical power collector layer by an electrode unit. Electrical resistance between the electrical power collector layer and an inspection electrode unit (6) is measured. An inspection electrode is in contact with a side part of the solid electrolyte layer. Another inspection electrode is in contact with other side part of the solid electrolyte layer. Electrical resistance between the two inspection electrodes is measured.    USE - Method for inspecting a short circuit of an all-solid-state battery i.e. lithium ion all-solid-state secondary battery, in a box/cylindrical/coin-shaped battery case. Uses include but are not limited to a mobile telephone, a notebook personal computer, a tablet terminal and an electric vehicle (EV).    ADVANTAGE - The method enables measuring the electrical resistance between the two inspection electrodes, so that the need to find out the occurrence of the short circuit in the electrodes unit can be eliminated, and the short circuit inspection can be avoided for each electrode unit, thus improving yield in the short circuit inspection of an all-solid-state battery and preventing deterioration of the yield.    DETAILED DESCRIPTION - The electrode active material layer is a positive electrode active material layer (2) and a negative electrode active material layer (4). The electrode unit is a single-sided coating positive electrode unit (10) and a single-sided coating negative electrode unit (20). An INDEPENDENT CLAIM is also included for a method for manufacturing an all-solid-state battery.
