To provide mounting structure of an antenna device which can finely adjust a mounting angle of the antenna device in a predetermined direction and with which firm mounting strength can be assured even when the antenna device is mounted using a small fixture.
The antenna device includes an arm 11, and an arm support member 18L, and the mounting fixture includes an arm mounting part 27. The arm mounting part 27 has a first reference hole P01 to be a reference, and a plurality of first through holes P10-P18 provided according to the mounting angle. The arm support member 18L has a second reference hole Q01 to be the reference, and a plurality of second through holes Q10-Q14 provided according to the mounting angle. The first through holes P10-P18 are provided by being shifted without being superimposed on one and the same straight line. A bolt 41a is inserted into the first reference hole P01 and the second reference hole Q01, and a bolt 43a is inserted into each one through hole selected according to the mounting angle from the plurality of first through holes P10-P18 and the plurality of second through holes Q10-Q14.
