1. An all-solid-state battery comprising:
a positive electrode current collector layer;
a positive electrode active material layer;
a negative electrode current collector layer;
a negative electrode active material layer;
a solid electrolyte layer disposed between the positive electrode active material layer and the negative electrode active material layer and formed of a solid electrolyte; and
both of (i) a first intermediate layer formed between the positive electrode current collector layer and the positive electrode active material layer, and (ii) a second intermediate layer formed between the negative electrode current collector layer and the negative electrode active material layer,
wherein the first intermediate layer and the second intermediate layer contain amorphous Li3V2(PO4)3.
