Abstract: An all-solid-state battery includes an electrode body in which a cathode layer that contains a cathode active material and a solid electrolyte, an electrolyte layer that is formed of the solid electrolyte, and an anode layer that contains an anode active material and the solid electrolyte are stacked in this order in an up-down direction, in which the cathode active material is a compound represented by a chemical formula Li2Fe(1-x)MxP(2-y)AyO7, contains at least one metal of Ti, V, Cr, Ni, and Co as the M in the chemical formula, and contains at least one element of B, C, Al, Si, Ga, and Ge as the A in the chemical formula, the x in the chemical formula satisfies 0.8
