Abstract
A drawn and ironed can made of resin-coated aluminum alloy includes a can body having a bottomed cylindrical shape. The can body includes a can bottom and a can barrel having a cylindrical shape. A height of the can body from a grounded part of the can bottom to an upper end of the can barrel is 151 mm to 160 mm. An outer diameter of the can barrel is 45 mm to 59 mm. The can barrel includes a tapered part formed in at least part of an area between 80 mm to 140 mm from the grounded part of the can bottom to the upper end of the can barrel. A plate thickness of the can barrel gradually increases inside the can barrel in the tapered part. An angle of the tapered part with respect to the can axis is 50 seconds to 1 minute and 30 seconds.
