The invention provides an organic/inorganic hybrid material and the method for manufacturing the same. A variety of functional monomers are co-polymerized to form a copolymer. The copolymer is subjected to sol-gel reactions with metal alkoxide oligomers to form an organic/inorganic hybrid material. The hybrid material has a high refractive index, a low moisture absorption, a high light transmission ratio, and a high glass transition point, such that the material can be applied in high light extraction efficient LED sealing materials, thin and light myopia/hypropia lens, portable projector lens, high brightness LCD prism films, solar cell refractive photoelectric conversion mirrors, and camera phone/digital camera lens.
