PROBLEM TO BE SOLVED: To provide a prepreg produced by using a polybenzazole fiber, generating extremely little bleeding of ion and suitable also in an electronic material field. SOLUTION: The prepreg is produced by combining a polybenzazole fiber having a two-point interference at a position of≥3 nm and≤12 nm as a long period on the meridian of a small-angle X-ray scattering pattern and a curable epoxy resin composition. The position to develop the two-point interference of the polybenzazole fiber is preferably≥5 nm and≤10 nm, and the higher-order components of the interference point are preferably confirmable from the first to the third components.
