摘要： A coated active material 110 includes a positive electrode active material 101 and a coating layer 104 coating at least a portion of a surface of the positive electrode active material 101. The coating layer 104 includes a first coating layer 102, which contains a first solid electrolyte, and a second coating layer 103, which contains a base material. The first coating layer 102 is located outside of the second coating layer 103. The first solid electrolyte contains Li, M, and X, where M is at least one selected from the group consisting of metalloid elements and metal elements other than Li, and X is at least one selected from the group consisting of F, Cl, Br, and I. A ratio of a specific surface area of the coated active material 110 to a specific surface area of the positive electrode active material 101 coated with the second coating layer 103 is less than or equal to 42%.
