Abstract: There is provided a transparent substrate which is excellent in dimensional stability, which significantly prevents the progress of a crack in an inorganic glass and the rupture of the inorganic glass, and which is excellent in flexibility. A transparent substrate according to an embodiment of the present invention includes: an inorganic glass having a thickness of 10 μm to 100 μm; and a resin layer on one side, or each of both sides, of the inorganic glass, wherein: a ratio of a total thickness of the resin layer to a thickness of the inorganic glass is 0.9 to 4; the resin layer has a modulus of elasticity at 25° C. of 1.5 GPa to 10 GPa; and the resin layer has a fracture toughness value at 25° C. of 1.5 MPa·m1/2 to 10 MPa·m1/2.
