PROBLEM TO BE SOLVED: To obtain a high-hardness non-rigid composite material as an organic/ inorganic composite material, having high surface hardness, being non-rigid, capable of being subjected to bending processing. SOLUTION: This high-hardness non-rigid composite material is an organic/ inorganic composite material comprising >=60 wt.% based on the whole amount of an inorganic composition including an aggregate component, having >=400 surface hardness by Vickers hardness (JIS Z 2,244) and >=R25 mm radius of curvature in which a laminar body having 3-15 mm thickness can be subjected to bending processing without break.
