A metal pipe for vehicle piping is manufactured by hot dipping a base metal pipe and is coated with a highly corrosion resistant coating formed by hot dipping. The metal pipe does not require any corrosion resistance improving coating, such as a paint coating or a resin coating. The coating of the metal pipe is formed of a hot dipping alloy containing 3% by weight or above Al, 1% to 15% by weight Mg and others including Zn and inevitable impurities.
