A structure body having the constitution in which the crystals of more than one types of brittle materials such as ceramics, metalloids, and the like are dispersed, a portion composed of the brittle materials is polycrystalline, the crystals constituting the polycrystalline portion substantially lacks the crystalline orientation, and boundary layers composed of glassy substances are substantially absent in the boundary face between the crystals. Accordingly, it is possible to obtain a structure body composed of more than one types of brittle materials and having novel properties without involving a heating/sintering process.
