Abstract: To provide a thermosetting resin composition which is useful for an antenna module capable of coping with a signal in a high-frequency band and having excellent mesh passability. Specifically disclosed is a thermosetting resin composition containing (A) a thermosetting resin and (B) at least one inorganic filler selected from the group consisting of a titanium-based inorganic filler and a zircon-based inorganic filler, in which in the component (B), a content of particles having a particle diameter of 1.0 μm or less is 30% by volume or less based on the component (B). And to provide a prepreg, a resin film, a laminate, a printed wiring board, an antenna device, an antenna module, and a communication device obtained by using the thermosetting resin composition.

Abstract: Provided is a production method of an FRP precursor. The method includes: a pre-coating step of applying a resin varnish having a filler content of 5 vol % or less in a solid content thereof, to a sheet-shaped aggregate, and a melt-pasting step of melt-pasting a pair of resin films, each having a filler content of 30 vol % or more, to both surfaces of the aggregate, after the pre-coating step.
