There is provided a method for producing an artificial retina in which an organic dye compound that induces a receptor potential responding to photostimulation is fixed on a polymer sheet substrate, comprising a bonding step of immersing the substrate in a solution containing the organic dye compound to chemically bond the organic dye compound to the substrate; a first washing step of washing with water the substrate to which the organic dye compound has been chemically bonded; and a second washing step of, after the first washing step, washing with an organic solvent the substrate to which the organic dye compound has been chemically bonded. Thus, there can be provided an artificial retina which has excellent mechanical properties such as elongation at break and good biocompatibility, and is capable of inducing a receptor potential responding to photostimulation with high sensitivity.
