摘要:
A method which enables an optical element having a large refractive index difference and a stabilized refractive index distribution to be produced in a short time. When a gel prepared by a sol-gel method is immersed in a solution containing at least one substance selected from the group consisting of an organic solvent, water, an acid, and an alkali, or in a solution having a metal salt dissolved in the at least one substance selected from the above group, a component eluted into the solution from the gel and/or a foreign substance which is produced or mixed in the solution during the solution immersing step is removed, and a component diffused into the gel from the solution is supplemented to the solution.
