Abstract
A polyamide resin composition for reflectors, which gives a molding having high mechanical strength and excellent heat resistance and which stably exhibits a high reflectance and can provide a reflector that resists a decrease in reflectance caused by heating, particularly in a LED production process and a reflow soldering process. A reflector obtained by molding the resin composition is also provided. The polyamide resin composition is composed of defined amounts of a polyamide resin (A), an inorganic filler (B) and a white pigment (C) (with the proviso that the total of the components (A), (B) and (C) does not exceed 100% by weight). The components of the polyamide resin (A) are defined and the polyamide resin (A) has a terminal amino group concentration of 70 to 230 mmol/kg.
