Resin composition, resin molded article and method for producing same

A resin molded article, comprising:

• a polyimide resin particle (A);
• and
• at least one selected from the group consisting of a thermoplastic resin (B) other than the polyimide resin particles (A) and a cured product of a thermosetting resin (C),
• wherein the polyimide resin particle (A) comprises a repeating structural unit of formula (1) and a repeating structural unit of formula (2),
• wherein R1 represents a divalent group having from 6 to 22 carbon atoms and comprising an alicyclic hydrocarbon structure,
• R2 represents a divalent chain aliphatic group having from 5 to 16 carbon atoms,
• X1 and X2 each independently represent a tetravalent group having from 6 to 22 carbon atoms and comprising an aromatic ring,
• a content ratio of the repeating structural unit of the formula (1) with respect to a total of the repeating structural unit of the formula (1) and the repeating structural unit of the formula (2) is 20 to 70 mol %,
• the polyimide resin particle (A) has a volume average particle size D50 of 5 to 200 μm, and
• the thermoplastic resin (B) is at least one selected from the group consisting of the following (B1) and (B2):
• (B1) an amorphous thermoplastic resin having a glass transition temperature that is lower than a melting point of the polyimide resin particle (A);
• and
• (B2) a crystalline thermoplastic resin having a melting point that is lower than the melting point of the polyimide resin particle (A).
