Abstract: A resin molded article includes a first resin formed of a polyolefin, reinforcing fibers, a second resin selected from a group consisting of a resin containing at least one of an amide bond and an imide bond, a resin containing an ester bond, and a resin having a linking group containing a sulfur atom, and a compatibilizer. The absolute value of difference in melting temperature between the first resin and the second resin is 130° C. or lower. At least a portion of the second resin forms domains in the first resin. The domains include first domains that do not contain the reinforcing fibers and second domains that contain the reinforcing fibers and that include a coating layer formed of at least a portion of the second resin on the periphery of the reinforcing fibers. The second domains include a second domain A containing one of the reinforcing fibers and a second domain B containing two or more of the reinforcing fibers.
