1. A method of producing a flexible optical wave guide consisting of a core made of a high refractive index transparent rubbery elastomer and a clad made of a low refractive index rubbery elastomer, which comprises extruding a high viscosity transparent core material through a nozzle, applying a low viscosity transparent liquid coating material to the extruded transparent core material, curing the core material and the coating material, applying a liquid clad material to the outer periphery of the coating material, and curing the clad material.
