The present invention relates to a composite electrode for an all-solid-state battery including ionic liquid, a manufacturing method thereof, and an all-solid-state lithium battery including the same and, more specifically, to a composite electrode for an all-solid-state battery which adds ionic liquid to an interface of a solid electrolyte and a composite anode when manufacturing a lithium all-solid-state battery cell including a solid electrolyte densified by undergoing a sintering process and a solid electrolyte material to apply a composite anode having lithium ion conduction properties to improve adhesion of the interface between the solid electrolyte and the composite anode and reduce interface resistance by filling pores in the composite anode with the ionic liquid, and an all-solid-state battery which allows high output/long life and high performance when using the same as an electrode of a battery, and directly affixes a densified solid electrolyte to a composite electrode without inserting an intermediate layer such as a polymer electrolyte between the solid electrolyte and the composite anode.(AA) Ionic liquid-added composite anode(BB) Polymer electrolyte(CC) Inorganic solid electrolyte(DD) CathodeCOPYRIGHT KIPO 2019
