PROBLEM TO BE SOLVED: To provide a small antenna device which has a simple configuration where antennas can be easily exchanged. SOLUTION: The antenna device includes a plurality of antennas 2 and 3 having characteristics different from each other, and a body 4 connected to one of the antennas to transmit a signal to the antenna. Each of the antennas has a first conductor 25 for emitting an electromagnetic wave, a second conductor 26 insulated from the first conductor, at least one antenna side feeding connection part 22 connected to the first conductor, and an antenna side grounding connection part 24 connected to the second conductor. The body has a plurality of body side feeding connection parts 11 for sending signals, and a body side grounding connection part 14 that is engaged with the antenna side grounding connection part. At least one portion of the body side feeding connection part to which at least one antenna side feeding connection part of one antenna is connected is different from at least one portion of the body side feeding connection part to which at least one antenna side feeding connection part of the two antennas is connected.
