    摘要： A method of producing an organic-inorganic composite material formed from an organic polymer and a metal alkoxide, comprising the steps of polycondensating the metal alkoxide through hydrolysis until the unreacted metal alkoxide is reduced to 3 vol. % or less, and mixing it with the organic polymer to form the organic-inorganic composite material. By laminating such organic-inorganic composite materials, the resulting laminate is provided with a concentration gradation wherein the metal element of the metal alkoxide is increased or decreased from one side to the other side of the laminate.
