A halogen-free flame-retardant polyolefin resin composition which can give a molded article improved in low-temperature resistance and surface whitening resistance and improved in flame retardancy and melt index, and an expansion-molded article having uniform and fine gas bubbles without large-sized gas bubbles, the halogen-free flame-retardant polyolefin-based resin composition containing a polyolefin resin, a dihydric or trihydric metal hydroxide surface-treated with a saturated fatty acid, or, when the metal hydroxide is aluminum hydroxide, aluminum hydroxide surface-treated with a saturated or specific unsaturated fatty acid or an alkali metal salt thereof, and an aluminum salt of an unsaturated fatty acid having 10 to 30 carbon atoms.
