PROBLEM TO BE SOLVED: To provide an antenna device which can achieve miniaturization while improving isolation between two antennas. SOLUTION: The antenna device is composed of an insulated substrate 2, a ground pattern 21 prepared on one side plane of the insulated substrate 2, two antenna elements 22a, 22b which are prepared on both sides of the insulated substrate 2 across the ground pattern 21 on one side plane of the insulated substrate 2 while one ends are connected to the ground pattern 21 and the other ends are opened, and a non-feeding element 32 which is prepared on the other plane of the insulated substrate 2 and faces to the ground pattern 21 and two antenna elements 22a, 22b across the insulated substrate 2. The non-feeding element 32 is installed facing feeding units 25a, 25b of the two antenna elements 22a, 22b across the insulated substrate 2 while being connected to the ground pattern 21.
