    摘要: The present invention is a polyamide resin composition which contains 50 to 90% by mass of a crystalline polyamide resin (A) and 9 to 49% by mass of a talc (B). The average particle size of secondary particles of the talc (B) in the polyamide resin composition is 30 μm or less. The polyamide resin composition has an exothermic peak present on a high temperature side of a maximum exothermic peak of a crystallization temperature during cooling in a cooling process of measurement by means of a differential scanning calorimeter. Variations in physical characteristics such as a molding shrinkage, mechanical characteristics, and a heat distortion temperature of the polyamide resin composition are suppressed among different production machines or different production lots. Consequently, characteristics within desired ranges are stably obtained.
