## Abstract

The invention relates to an inorganic-organic hybrid material which comprises an inorganic component and an organic component, has a content of the inorganic component of 20-80% by mass, and has a refractive index of 1.60 or higher, wherein, when preparing a strip specimen having a thickness of 1,000 μm, a width of 5 mm and a length of 70 mm by using the inorganic-organic hybrid material and winding the specimen by 180° on a cylindrical metal rod having a diameter of 10 mm at 25° C., the specimen does not crack.
