Abstract
A thermoplastic resin composition of which the molding efficiency can be improved by a high flowability and a high crystallization temperature while ensuring desired physical properties (e.g., strength) in a molded product, and a molded product of the composition are provided.The thermoplastic resin composition comprises a plurality of thermoplastic resins having a melt viscosity different from each other and containing a unit which comprises an arylene group and an ether group and/or a carbonyl group; when the thermoplastic resin composition at least comprises a first thermoplastic resin having a melt viscosity of 150 to 1500 Pa·s at a temperature of 400° C. and a shear rate of 1216 s−1, and a second thermoplastic resin, and the melt viscosity ratio of the first thermoplastic resin relative to the second thermoplastic resin at a temperature of 400° C. and a shear rate of 1216 s−1 [the former/the latter] is 1.5/1 to 10/1.
