description In a manufacturing process of a positive electrode active material for a power storage device, which includes a lithium silicate compound represented by a general formula Li2MSiO4, heat treatment is performed at a high temperature on a mixture material, grinding treatment is performed, a carbon-based material is added, and then heat treatment is performed again. Therefore, the reactivity between the substances contained in the mixture material is enhanced, favorable crystallinity can be obtained, and further microparticulation of the grain size of crystal which is grown larger by the high temperature treatment and crystallinity recovery are achieved; and at the same time, carbon can be supported on the surfaces of particles of the crystallized mixture material. Accordingly, a positive electrode active material for a power storage device, in which electron conductivity is improved, can be manufactured.
