PROBLEM TO BE SOLVED: To provide an on-vehicle diversity antenna device, with which proper reception sensitivity can be expected at all the time and a restriction of a mounting position or adverse effects on appearance can also be reduced. SOLUTION: On a front glass pane 2 of a vehicle 1, two first antenna elements 10, 11 and two second antenna elements 12, 13 are arranged distributed and digital signals received by the antenna elements 10-13, respectively, are supplied to a diversity combination circuit 20 so as to produce a combined signal. The first antenna elements 10, 11 include radiating conductive parts 10a, 11a extending downward from an upper end of the front glass pane 2, and horizontal conductor parts 10b, 11b extending horizontally from distal ends of the radiating conductive parts 10a, 11a.
