PURPOSE: To obtain an aluminum sheet capable of high-speed press molding even without applying a press oil thereto. CONSTITUTION: A lubricated aluminum sheet is produced by forming a chromate film on the surface of an aluminum sheet and forming a lubricating film comprising a water-dispersed polyurethane resin, silicon compound particles and a lubricant on the chromate film. The mean particle diameter of the silicon compound particles in the lubricating film is 0.05-4.0μm, and the lubricant contains a natural wax. This sheet is therefore excellent in corrosion resistance and tight adhesion of coating and can be effectively used as a material for household electric appliances, building materials, containers, etc.
