<p>In a cabinet for electronic apparatus, when Mg-Li alloy is employed to reduce weight of the cabinet and depressions are molded on a surface of the cabinet through presswork by using the Mg-Li alloy, neither a rough surface nor a crack appears in any bent portion forming the depressions of the cabinet. In a cabinet for electronic apparatus including a bump shape including at least one surface formed by conducting presswork for magnesium-lithium alloy, the bump shape is a shape in which a new surface formed when a reference surface before the presswork of the magnesium-lithium alloy is pushed toward the inside of the cabinet by the presswork and is placed apart from the reference surface is surrounded by the reference surface, the surface has a plate thickness t (mm) in a range of 0.4@t@2.0, and at least one bent portion constituting the bump shape has a radius of curvature R (mm) in a range of t@R.</p> |
