A composite composition that has a negative thermal expansion coefficient and can easily realize a composite having a desired thermal expansion coefficient, for example, a thermal expansion coefficient close to zero, by mixing with another composition, The composite composition is formed by molding the composite composition into a predetermined shape, and has a desired thermal expansion coefficient, for example, a thermal expansion coefficient close to zero, and various characteristics such as high strength and low humidity expansion coefficient. To provide a body. A composite composition of the present invention includes a fibrous filler and a resin material, and is a composite composition that can be molded into a predetermined shape to produce a composite, which is used for the composite composition. The fibrous filler to be obtained is composed of a polysaccharide material. On the other hand, the resin material used in this composite composition is capable of dispersing the fibrous filler so that the average fiber diameter is 100 μm or less, and has a hydrogen atom content capable of forming a hydrogen bond. It is less than 0.01 mol / g. [Selection figure] None |
