Abstract

A press-molded product includes: carbon fibers having a weight average fiber length of 1 mm or more; a polyamide-based resin (X); and a polyarylene ether-based resin (Y). The carbon fibers include carbon fiber bundles. The polyamide-based resin (X) and the polyarylene ether-based resin (Y) form a sea-island structure inside and outside the carbon fiber bundles. In the sea-island structure, one of the polyamide-based resin (X) and the polyarylene ether-based resin (Y) forms a sea phase and the other forms an island phase having a particle diameter Dr of 0.05 μm or more and less than 50 μm.
