摘要
<p>PROBLEM TO BE SOLVED: To provide a prepreg having high front/rear identification property.SOLUTION: A prepreg 10 of the present invention comprises: a fiber substrate 1; a first resin layer 2 provided on one face of the fiber substrate 1; and a second resin layer 3 provided on the other face of the fiber substrate 1. The second resin layer 3 contains light-shielding pigment. The first resin layer 2 contains coloring agent of a different type from the light-shielding pigment. Color of the prepreg 10 seen from a normal direction of a surface of the first resin layer 2 is different from color of the prepreg 10 seen from a normal direction of a surface of the second resin layer 3.</p>
