Abstract:
A prepreg includes a resin layer constituted by a half-cured product of a thermosetting resin composition, and a fibrous substrate provided in the resin layer. A prepreg test piece that is a cured product obtained by heat curing the thermosetting resin composition has a maximum value of 400 kPa or less for thermal shrinkage stress measured by a predetermined thermal stress test.

Claim (Index 2):
A prepreg comprising a resin layer constituted by a half-cured product of a thermosetting resin composition, and a fibrous substrate provided in the resin layer,\n wherein a prepreg test piece that is a cured product obtained by heat curing the thermosetting resin composition and has a thickness of 0.1 mm has a maximum value of 100 kPa or less for thermal expansion stress, the thermal expansion stress being obtained by holding the prepreg test piece at both ends by jigs and measuring, as the thermal expansion stress, tensile stress between the jigs, and the tensile stress being measured during a period which a temperature of the prepreg test piece is raised from normal temperature to 260\u00b0 C. while a distance between the jigs is changed in a range from 0.01 ppm/\u00b0 C. to 5 ppm/\u00b0 C., inclusive, by allowing the jigs to separate from each other.
