Abstract

In an all-solid-state battery using an electrode containing a sulfide-based solid electrolyte, corrosion of a current collector is suppressed, and the resistance of the electrodes is prevented from increasing. An electrode for an all-solid-state battery according to the present invention includes: a mixture containing an active material and a sulfide-based solid electrolyte; and a current collector, wherein the current collector is made of an alloy containing Ni and Cr, a Ni content in the alloy is 60% by mass or more, and a Cr content in the alloy is 0.1% by mass or more and 40% by mass or less. An all-solid-state battery according to the present invention includes: a positive electrode; a negative electrode; and a solid electrolyte layer, wherein at least one of the positive electrode and the negative electrode is the electrode for an all-solid-state battery according to the present invention.
