PROBLEM TO BE SOLVED: To provide a diversity antenna that decreases the gain difference between horizontally polarized waves and vertically polarized ones in each antenna, that makes the directivity of each antenna closer to non-directivity, and that is adaptable to the difference of the polarized waves. SOLUTION: A first inverted F type antenna 10 and a second inverted F type antenna 20 are arranged in such a way that each central axis of a first longitudinal conductor 11 and a second one 21 becomes roughly perpendicular to each other, each central axis of a first feeding conductor 13 and a second one 23 becomes roughly parallel to each other, the first longitudinal conductor 11 and the second one 21 face outside, and a fist printed board 14 and a second one 24 are made to face each other in such a way as to become roughly parallel.
