Original Abstract Submitted

A flat lithium primary battery includes a case, a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte. The positive electrode includes a positive electrode pellet containing positive electrode active material, conductive agent, and binder. The positive electrode pellet has a circular columnar shape having a side circumferential surface extending in a circumferential direction surrounding a center axis extending in a center axis direction. The conductive agent contains graphite. The positive electrode pellet is divided into first and second portions. The first portion includes at least a part of the side circumferential surface of the circular columnar shape. The first portion includes an annular portion surrounding at least a part of the second portion. A content of the graphite in the second portion of the positive electrode pellet is higher than in the first portion of the positive electrode pellet.
