Abstract
Provided are: a resin fiber sheet and a prepreg which use a laminated sheet as a raw material and which achieve excellent heat resistance, dielectric constant, dielectric loss tangent and dimensional stability (little warping); and a method for producing a prepreg using the resin fiber sheet. In one embodiment of the present invention, provided is a resin fiber sheet constituted from a poly(phenylene ether) composition fiber. The poly(phenylene ether) composition fiber contains more than 0 mass % and not more than 95 mass % of a poly(phenylene ether) and a total of not less than 5 mass % and less than 100 mass % of a liquid crystal polyester and/or a syndiotactic polystyrene, and has a single fiber diameter of 1-50 μm.
