PROBLEM TO BE SOLVED: To provide an aluminum plated steel sheet joined by using resistance welding represented by spot welding used for automobile parts or the like, and to provide worked parts obtained by using the aluminum plated steel sheet. SOLUTION: In the aluminum plated steel sheet having excellent resistance weldability, two or more kinds of intermetallic compound layers different in compositions essentially consisting of Fe and Al are present on the surface of the steel sheet in layers, and the mean Fe concentration up to 5μm from the surfaces of the intermetallic compound layers is, by mass,≥30%. The worked parts are obtained by using the aluminum plated steel sheet having excellent resistance weldability. COPYRIGHT: (C)2004,JPO
