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 10):
A method for measuring thermal stress of a wiring board material, the method comprising:\n holding both ends of a test piece constituted by the wiring board material by jigs, respectively, and measuring tensile stress between the jigs which is defined as thermal shrinkage stress, the tensile stress being measured during a period which a temperature of the test piece is lowered from 260\u00b0 C. to normal temperature after the test piece is heated to a temperature of 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 come closer to each other.
