A multi-band antenna is provided to obtain broadband width while achieving a compact size of a device by varying a shape and a position of a second antenna element and arranging an antenna element in a remaining space of a substrate. A first antenna device(210) is formed on a first substrate, and resonates at a first frequency band by being connected to a feeding part of the antenna. A second antenna device(230) is formed on the first substrate and induces capacitive coupling with the first antenna device, and resonates at a second frequency band by being grounded as being connected to the feeding part. At least a part of the second antenna device is formed on a second substrate(130) adjacent to the first substrate. The second substrate is embedded in a terminal, and the first substrate is comprised in the outside of the terminal.
