The present invention relates to a seamless can having a bottom section and a body section, wherein a thermoplastic resin coating is formed on an outer surface side of the can over a polyester-based paint film, characterized in that the polyester-based paint film includes a polyester-based paint composition which contains a colorant in an amount of 20 parts by mass or less relative to 100 parts by mass of a total resin solid content and a curing agent in an amount of 5 to 43 parts by mass relative to 100 parts by mass of a polyester resin; and an entire outer surface of the can including the bottom section is colored. Without compromising the processability and adhesion of the resin coating, a seamless can which is colored in its entirety including the bottom section of the can without undergoing a printing process is provided.
