A polytrimethylene terephthalate resin composition is provided to secure excellent impact resistance and high rigidity and to be applicable to the molded product such as mobile communication devices and electronic devices. A polytrimethylene terephthalate resin composition comprises 10-70 parts by weight of long fiber filler based on 100.0 parts by weight of the sum of polytrimethylene terephthalate resin and long fiber filler. The long fiber filler has the length of 5-30 mm. The inherent viscosity [eta] measured at 25°C under an o-chloro phenol solvent is 0.36-1.6. The long fiber filler is at least one fiber selected from a group consisting of long glass fiber, long carbon fiber, long metal fiber, long aramid fiber, long boron fiber, long basalt fiber and long natural fiber.
