Abstract

A coated active material 100 of the present disclosure includes a positive electrode active material 101 and a coating layer 102 including a first solid electrolyte and coating at least a portion of a surface of the positive electrode active material 101. The first solid electrolyte contains Li, Ti, M, and X, the M is at least one selected from the group consisting of metalloid elements and metal elements other than Li and Ti, and the X is at least one selected from the group consisting of F, Cl, Br, and I. A quotient obtained by dividing a ratio (%) of a mass of the first solid electrolyte to a total mass of the positive electrode active material 101 and the first solid electrolyte by a specific surface area (m<2>/g) of the positive electrode active material 102, which is determined by the following mathematical expression (A), is 1.9 or more and 6.9 or less. Mathematical expression (A): {(mass of first solid electrolyte)/(total mass of positive electrode active material and first solid electrolyte)} × 100/(specific surface area of positive electrode active material)
