A metal band having metallic appearance and being excellent in forming stability is provided. The metal band includes a coating film containing not less than 20 mass % in the coated and dried state, of filler of aluminum or aluminum alloys on the side thereof corresponding to the outside of a can. The metal band also has a resin-rich portion containing not more than approximately 5 mass % of the filler, approximately 0.1 to 20 μm in thickness in the coated surface far from the metal strip surface, seamlessly-formed can bodies made of such strips. Methods for manufacturing such strips and can bodies are also provided.
