Abstract
In the present invention, there is provided a polyamide resin composition for portable electronic devices, which is excellent in mechanical strength, thin-wall moldability, crystallinity and warping property.A polyamide resin composition comprising 30 to 80% by weight of a polyamide MP (A), 20 to 70% by weight of a polyamide resin (B) having a melting point not less than 245° C. (with the total amount of both being 100% by weight). The composition additionally comprises a filler (C) comprising a fibrous filler (C1) as an optional component and a plate-like filler (C2) as an essential component, wherein a content ratio (C1):(C2) is 0:10 to 9:1. The filler (C) is present in an amount of 30 to 250 parts by weight per 100 parts by weight of the sum of the polyamide MP (A) and the polyamide resin (B). The polyamide MP (A) is a polyamide resin obtained by polycondensation of a mixed diamine, which comprises 90 to 50% by mole of metaxylylenediamine and 10 to 50% by mole of paraxylylenediamine, with an α,ω-linear aliphatic dibasic acid and/or an aromatic dibasic acid.
