Abstract:
A polyimide precursor solution contains resin particles and a polyimide precursor. The resin particles in the polyimide precursor solution have a volume particle size distribution with one or more peaks. The volume frequency of a peak having the highest volume frequency of the one or more peaks accounts for 90% to 100% of the total volume frequency of all peaks of the volume particle size distribution.
