A positive electrode material 10 includes a positive electrode active material 101, a coating layer 102, and a second solid electrolyte 105. The coating layer 102 contains a first solid electrolyte and coats at least a portion of a surface of the positive electrode active material 101. The first solid electrolyte contains Li, Ti, M, and X, where M is at least one selected from the group consisting of metalloid elements and metal elements other than Li or Ti, and X is at least one selected from the group consisting of F, Cl, Br, and I. The second solid electrolyte 105 is in indirect contact with the positive electrode active material 101 with the coating layer 102 disposed between the second solid electrolyte 105 and the positive electrode active material 101. A percentage of coverage of the surface of the positive electrode active material 101 with the coating layer 102 is greater than or equal to 65%.
