There is provided a production method of composite particles, by which the fine composite particles which contain fine fibers in the particles, are spherical and have a particle size of 1 mum or less can be stably obtained. It is characterized in that when the composite particles containing fine fibers in the particles are produced, a water-soluble metal salt is dissolved in an aqueous solution in which the fine fibers have been dispersed, and that an alkali which reacts with a metal ion dissolved in the aqueous solution to deposit a metal compound is thereafter added to the aqueous solution while maintaining dispersion of the fine fibers, thereby depositing the composite particles containing the fine fibers and comprising the metal compound.
