摘要：
The present invention addresses the problem of improving the bundling properties of inorganic fibers coated with a sizing agent for inorganic fibers, and of shortening the hardening treatment duration when producing a fiber-reinforced resin composite material. This sizing agent for inorganic fibers comprises a resin (A) containing a vinyl ester resin and ionic polyester resin, and the mass ratio of the vinyl ester resin to the ionic polyester resin is more than 1.
