Abstract
An anode mixture contains a plurality of carbon particles and a plurality of Si-based particles. The plurality of carbon particles includes a plurality of scaly graphite particles doped with boron. The content of the plurality of Si-based particles relative to the plurality of carbon particles is 5 mass % to 60 mass %. The content of the plurality of scaly graphite particles relative to the plurality of carbon particles is 1.5 mass % or more.
