1. An antenna device comprising:
a substrate having an insulating base member and a conductor arranged on the insulating base member;
an antenna having:
a main plate arranged on the insulating base member as at least a part of the conductor and providing a ground potential;
a patch portion arranged to face the main plate in a plate thickness direction of the substrate; and
a metal member provided separately from the conductor,
wherein
the substrate has a no-arrange region in which the conductor is not arranged, which is a region from a periphery of the substrate to the main plate in a plan view,
the metal member is in contact with the no-arrange region on a top surface or on a bottom surface opposite to the top surface in the plate thickness direction of the substrate, and
a housing is formed by using a resin material for radiating a radio wave and the metal member.
