Patent ID: 7960464

Claim:
A thermoplastic resin composition comprising a polymer alloy, in which at least polybutylene terephthalate resin and a polycarbonate resin are mixed, and a filler, wherein said filler is the following inorganic particles (a) and/or glass fibers (b), and said polymer alloy forms a co-continuous structure with a wavelength of concentration fluctuation of 0.001 to 5 pm or a dispersed structure with a distance between particles of 0.001 to 5 pm; (a) inorganic particles with a number average particle size of 10 μm or less, as measured by the laser diffraction method; (b) glass fibers, not less than 60 wt % of which in the thermoplastic resin composition have their fiber lengths kept in a range from 0.1 to 1 mm; wherein in the case where the infrared absorption spectrum of the polymer alloy is measured, the intensity ratio of the absorption peak appearing in a range of 2933±5 cm −1 to the absorption peak appearing in a range of 2965±5 cm −1 is 0.43 or more.
