Abstract
A flame-retardant composition that is not colored during compounding and molding, and a covered electric wire using the same. The flame-retardant composition contains at least a matrix polymer such as an olefin resin, a phenolic antioxidant having tert-butyl groups in positions 2 and 6 of a hydroxyl group, and a flame retardant that is a pulverized natural mineral containing magnesium hydroxide as the main ingredient, and the iron oxide concentration in the flame retardant is 1000 ppm or less. The covered electric wire uses the flame-retardant composition as a covering material.
