摘要： 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.
