description	An objective of the present invention is to provide an all-solid-state battery with a high discharge capacity in which lithium vanadium phosphate is used as a positive electrode active material layer and a negative electrode active material layer. According to the present invention, the positive electrode active material layer and the negative electrode active material layer of the all-solid-state battery having an all-solid-state electrolyte between a pair of electrodes contain the lithium vanadium phosphate, the lithium vanadium phosphate contains a polyphosphate compound containing Li and V, and the lithium vanadium phosphate contains Li3V2(PO4)3 as a main phase and contains 1.0% by weight or more and 15.0% by weight or less of Li3PO4 relative to Li3V2(PO4)3, whereby a high discharge capacity can be provided.
