Abstract

To provide a chassis for a small electronic device that can be formed efficiently by drawing work with low cost, is hard to cause forming failure, and causes no damage on the surface thereof on forming to provide an excellent appearance. The rolled aluminum alloy laminated sheet material is for forming a chassis for a small electronic device by drawing work, and contains a rolled aluminum alloy sheet material having a 0.2% proof stress of 200 MPa or more, and a covering material laminated at least one surface of both surfaces of the rolled aluminum alloy sheet material, and the covering material contains any one of a synthetic resin film, and a laminated material containing a metal foil having synthetic resin films laminated on both surfaces thereof. The rolled aluminum alloy sheet material may have a fibrous crystalline structure extending in a direction perpendicular to a thickness direction thereof.
