The silicate composite particle contains silicate phases, silicon particles dispersed in the silicate phases, and a carbon phase. The silicate phases contain at least one selected from the group consisting of an alkali metal and an alkaline earth metal. At least parts of the carbon phase coat at least parts of surfaces of the silicon particles.",
