1. A vehicle antenna device that includes a plurality of antennas in an accommodating space surrounded by a case and an antenna base, and that has a height of 70 mm or less from an outer surface of a vehicle when attached to the outer surface of a vehicle, the vehicle antenna device comprising:
a first substrate on which a first patch antenna is mounted; and
a second substrate on which a second patch antenna is mounted,
wherein the first substrate is provided at a position higher than the second substrate,
wherein a receiving circuit part configured to demodulate a received signal received by the second patch antenna and to output a demodulated signal as a digital signal is mounted on the first substrate.
