Provided is a method of producing a composite optical element, including performing stress removal after molding a composite optical element by integrating a resin material with one surface of a glass material in a heated state, in which, after the composite optical element prepared in the molding is cooled to a first cooling temperature lower than a glass transition temperature of the resin material, an interface layer of the resin material, the interface layer contacting the glass material, is heated to a temperature equal to or higher than the glass transition temperature of the resin material, by causing infrared light having a wavelength region in which an infrared absorptivity of the resin material is higher than that of the glass material to enter from another surface of the glass material, and then the composite optical element is cooled to a second cooling temperature lower than the first cooling temperature.
