<p>A carbon fiber reinforced substrate (21, 41) comprising a fabric (25, 45) composed of carbon fiber bundles and a first resin (24, 44) adhering to said fabric (25, 45), wherein said carbon fiber bundles respectively comprise numerous continuous carbon filaments, the tensile modulus of said carbon fiber bundles is 210 GPa or more, the fracture strain energy of said carbon fiber bundles is 40 MJ/m3 or more, and the amount of said first resin (24, 44) adhering to said fabric (25, 45) is in a range from 1 to 20 parts by weight per 100 parts by weight of said fabric (25, 45), characterized in that said fabric (25, 45) is a uni-directional woven fabric (51, 61) and said first resin (24, 44) is adhered relatively more densely on a surface of said uni-directional woven fabric (51, 61) than in the inside of said carbon fiber bundles, in such a state that said first resin (24, 44) of 70 vol% or more exists and is studded discontinuously on the surface of said uni-directional woven fabric (51, 61).
