Abstract

Composite positive electrode active material particles, a method of manufacturing composite positive electrode active material particles, and a solid-state battery. The composite positive electrode active material particles contain: positive electrode active material particles; a first coating layer coating at least a part of the positive electrode active material particles; and a second coating layer coating at least a part of the first coating layer, wherein the first coating layer contains an oxide, the second coating layer contains a sulfide solid electrolyte, the sulfide solid electrolyte contains an argyrodite-type sulfide, and a 10% particle diameter D10 in a volume-based cumulative particle size distribution is 3.3 µm or less.
