Abstract: The present invention provides a polyamide composition for a reflector having high heat resistance and good mechanical properties, having excellent adhesion to a sealing material for an LED package, and capable of retaining a high reflectance even after exposure to heat and light intended for the production process of the LED package and the environment in which the reflector is used in the LED package, when it is molded. The present invention is a polyamide composition for a reflector, containing: 30 mass % or more of a polyamide (A) having a melting point of 280° C. or higher; and 25 mass % or more of titanium oxide (B). The total content of the polyamide (A) and the titanium oxide (B) is 75 mass % or more.

Abstract: A polyamide resin composition includes: 100 parts by mass of (A) a polyamide having a melting point of 280 to 330° C.; 0.5 to 80 parts by mass of (B) aluminum diethylphosphinate; 0.2 to 2 parts by mass of (C) at least one phosphorous acid ester represented by formula (6) or (7); and (E) at least one reinforcing material. A mass ratio of the at least one phosphinic acid salt (B) to the at least one phosphorous acid ester (C) ((B)/(C)) is in a range of from 10 to 100. An average particle diameter of the phosphinic acid salt (B) is 0.1 to 100 μm. The polyamide resin composition does not comprise a metallic soap-based lubricant.
