Abstract: Disclosed are a material for an optical waveguide, which has high polymerizability and high solvent resistance, an optical waveguide made of the material, and a method for manufacturing the optical waveguide. When a material for an optical waveguide from which organic material layers are made is irradiated with an energy beam, it is activated to make a cladding and a core. The material comprises an oxetane compound, an oxirane compound, and a cationic polymerization initiator. Since the oxetane compound has an oxetane ring, it has a high repeated reactivity in a chain reaction. Thus, the material has high polymerizability at the time of a chain reaction, so that a polymer having an increased mechanical strength and a high solvent resistance is produced. The oxetane compound and the oxirane compound have high compatibility with each other and the refractive index of each of the compounds is reflected in the refractive index of a cured mixture.
