Abstract: Provided are an all-solid state battery with a better quality of contact among particles of an active material and with an enhanced discharge capacity; an electrode for an all-solid state battery; and a method of manufacturing the same. The all-solid state battery is manufactured through the steps of: causing a deliquescent solid electrolyte to deliquesce, the deliquescent solid electrolyte having ionic conductivity, electronic conductivity and a deliquescent property; preparing an electrode mixture by mixing the deliquescent solid electrolyte having deliquesced and an active material together; heat-treating and shaping the electrode mixture to produce an electrode; and bonding the thus-produced electrode and a solid electrolyte layer with the solid electrolyte layer interposed between the electrode and another electrode which are paired to serve as a positive electrode and a negative electrode.
