Abstract
Aromatic polyether microparticles contain a plurality of particles containing an aromatic polyether in which a content of the particles having a particle diameter equal to or smaller than 50 μm to a total volume of the aromatic polyether microparticles is equal to or higher than 50% by volume. The aromatic polyether microparticles contain phenolic hydroxyl groups in a content equal to or greater than 80 μmol/g.
