Abstract

To provide an aluminum can made of a composite member of a component of a JIS5000-series aluminum alloy and a component of a JIS3000-series aluminum alloy, and a bottle-shaped aluminum can made of only JIS3000-series aluminum alloy capable of being easily identified.SOLUTION: A bottle-shaped aluminum can has a recycle indication 60 which is provided on a bottle-like body 21 and indicates that the bottle-like body is manufactured only from an aluminum recycled lump manufactured by using a used aluminum can. The recycle indication 60 has, for example, a description portion 61, and a code portion 62 which can be read by an optical reader. The description portion 61 informs a general consumer, a dealer and the like that a used aluminum can is used as a production raw material on account of effective utilization of resources and that this aluminum can is collected after use and is recycled again as a production raw material for an aluminum can. In the description portion 61, for example, characters "100% recycle" are described.SELECTED DRAWING: Figure 2
