COMPOSITE COMPOSITION AND COMPOSITE

PROBLEM TO BE SOLVED: To provide a composite composition that has a negative coefficient of thermal expansion and can easily achieve the production of a composite having a desired coefficient of thermal expansion, for example, a near zero coefficient of thermal expansion, by mixing other compositions and to provide a composite that is produced by molding the composite composition into a predetermined shape and has a desired coefficient of thermal expansion, for example, a near zero coefficient of thermal expansion, and various properties of high strength and a low coefficient of humidity expansion. SOLUTION: The composite composition includes a fibrous filler and a resin material and can produce a composite by molding the composite composition into a predetermined shape. The fibrous filler used in the composite composition is composed of a polysaccharide material. The resin material used in the composite composition is characterized in that it can disperse the fibrous filler so that the average fiber diameter of the fibrous filler is reduced to not more than 100 μm and that the content of hydrogen atom which can form a hydrogen bond is less than 0.01 mol/g.
