The invention belongs to the technical field of electrochemistry, and particularly relates to an all-solid-state thin film battery. The all-solid-state thin film battery comprises a positive electrode layer, a negative electrode layer, an all-solid-state diaphragm layer and a flexible battery polar plate, wherein the positive electrode layer and the negative electrode layer are positioned in the same plane; a gap is formed between the positive electrode layer and the negative electrode layer; the positive electrode layer is formed by mixing a positive electrode active material, a solid electrolyte, a conductive additive and a binder according to a certain process; the negative electrode layer is formed by compounding graphite and a solid electrolyte, or consists of lithium metal and Li-Al, Li-In and Li-Sn alloy; the all-solid-state diaphragm layer is composed of a solid electrolyte with ultrahigh ionic conductivity; the flexible battery pole plates are respectively composed of ultrathin aluminum foils and copper foils; and the contact sides of the solid electrolyte layer and the positive electrode and the negative electrode adopt latticed extension structures. According to the invention, the risk of contact short circuit caused by the stacking structure of the positive electrode layer and the negative electrode layer is fundamentally avoided, and the ionic conductivity is greatly improved.
