<P>PROBLEM TO BE SOLVED: To provide a prepreg that has excellent impregnation properties of a thermosetting resin composition into a woven fabric while maintaining various characteristics which the prepreg has. <P>SOLUTION: The prepreg 40 is obtained by impregnating a woven fabric comprised of strands with a resin composition. In the prepreg, silica particles are present in the strands. Thus, the prepreg having excellent impregnation properties of the resin composition into the woven fabric can be obtained. Also a metal-clad laminate using the prepreg and further a printed wiring board and a semiconductor device using them can be obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
