The coating layer () includes a lithium-containing fluoride. When a mass of the lithium hydrogen carbonate present on the surface of the positive electrode active material () is measured by thermogravimetry-mass spectrometry, a proportion R of the mass of the lithium hydrogen carbonate in a mass of the positive electrode active material () is 130 ppm or more and 580 ppm or less.",
