Organic-inorganic composite particles including: inorganic particles; and an organic polymer, wherein the inorganic particles have surfaces on which no modification treatment for introducing a polymerizable reactive group is conducted, the organic polymer comprises a hydrophilic block arranged on the surfaces of the inorganic particles and made of a first polymer, and a hydrophobic block stacked on an outside of the hydrophilic block and made of a second polymer, and the inorganic particles, the first polymer, and the second polymer have surface free energies satisfying a condition expressed by the following formula:n n E NP >E A >E B n n[in the formula, E NP represents the surface free energy of the inorganic particles, E A represents the surface free energy of the first polymer, and E B represents the surface free energy of the second polymer]. |
