Abstract: Provided is a resin composition having improved fluidity in a molten state maintained without lowering heat resistance, containing: a polymer being a reaction product of a first organic compound having a phenolic hydroxyl group and a second organic compound having a glycidyl group, Mw of the polymer being no greater than 10,000; and a thermoplastic resin other than the polymer. A proportion of the polymer contained in the resin composition is from 0.1% to 30% by mass. A melting point of the thermoplastic resin is no less than 200° C. The thermoplastic resin has a benzene ring in a molecule. The polymer and the thermoplastic resin have blended to form a homogeneous phase. Also provided are a molded product formed from the aforementioned resin composition, and a production method of a molded product including: kneading the resin composition by chaotic mixing; and molding a kneaded product obtained after the kneading.
