The lithium rechargeable battery of the present invention is provided with a current collector and an active material layer containing active material particles 10 supported on this current collector. The active material particles 10 are secondary particles 14 in which a plurality of primary particles 12 of a lithium transition metal oxide are aggregated, and have a hollow structure that contains a hollow section 16 formed inside the secondary particle 14 and a shell section 15 that surrounds the hollow section 16. A through hole 18 that penetrates from the outside to the hollow section 16 is formed in the secondary particle 14. The ratio (A/B) in a powder x-ray diffraction pattern of the active material particles 10, where A is the full width at half maximum of the diffraction peak obtained for the (003) plane and B is the full width at half maximum of the diffraction peak obtained for the (104) plane, satisfies the equation (A/B)≦0.7.
