1. A light waveguide forming method comprising the steps of:

  • disposing a light waveguide forming substrate having a conductive thin film and a photosemiconductor thin film in this order on an insulative substrate so that at least the photosemiconductor thin film of the light waveguide forming substrate is in contact with an aqueous electrolyte solution containing film forming material having a property that solubility or dispersibility in a water solution decreases according to change of its pH; and

    applying a voltage between a selected region of the photosemiconductor thin film and a counter electrode by irradiating the selected region of the photosemiconductor thin film with light to deposit the material on the selected region of the semiconductor thin film.
