Abstract

The present invention is a polyamide resin composition containing 50 to 90% by mass of a crystalline polyamide resin (A) and 9 to 49% by mass of a talc (B), and preferably further containing a coupling agent (C) and a fatty acid metal salt (D), in which an average particle size of secondary particles of the talc (B) in the polyamide resin composition is greater than 30 μm. The polyamide resin composition is less likely to cause a poor appearance of a molded article or occurrence of sink marks, and can stably provide characteristics within desired ranges.
