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.
