PROBLEM TO BE SOLVED: To provide a photocurable prepreg sheet which has good handleability, shape followability, reinforcing ability and storage stability, causes no blocking even when the protection film has a hole, generates little waste and allows the used resin to be recyled or incinerated. SOLUTION: The photocurable prepreg sheet A is composed of a photocurable radically polymerizable resin composition and a reinforcing fiber and contains thermally prepregged prepreg layer 1. Surface protection film 2 is composed of light shielding film 22 and inner film 21 releasably integrated with each other to overlie the surface of prepreg layer 1 with inner film 21 facing prepreg layer 1. Back surface protection film 5 composed of a 30-100μm-thick polyolefinic resin film is laminated on the back surface of prepreg layer 1. COPYRIGHT: (C)2008,JPO&INPIT
