Provided is a polyamide composition comprising 100 parts by weight of (A) a polyamide having dicarboxylic acid units containing 60 to 100 mol % of terephthalic acid units, and diamine units containing 60 to 100 mol % of 1,9-nonanediamine units and/or 2-methyl-1,8-octanediamine units, and 5 to 100 parts by weight of (B) a titanium oxide with an average particle size of 0.1 to 0.5 &#x3bc;m. The polyamide composition shows excellent heat resistance enough to withstand the SMT process, and gives a molded article with excellent whiteness and surface-reflectance.
