An object of the present invention is to provide a method for producing an olivine-type silicate compound such as Li 2 FeSiO 4 useful as a positive electrode active material for a lithium ion battery by hydrothermal reaction without using chloride as a raw material. An organic acid transition metal salt represented by a lithium compound, a silicate compound, and (R) 2 M (wherein R represents an organic acid residue and M represents Fe, Ni, Co, or Mn). Li 2 MSiO 4 (wherein, M represents one or more selected from Fe, Ni, Co, and Mn), characterized by hydrothermal reaction of a basic aqueous dispersion containing Process for producing an olivine-type silicate compound.
