1. An antenna device comprising:
a substrate;
a feed element that is disposed at a first position on the substrate and configured to supply power;
a first parasitic element that is disposed on the substrate at a second position different from the first position of the feed element, from a plan view, and is electromagnetically coupled with the feed element;
a dielectric member that is disposed so as to at least partially cover the feed element and the first parasitic element as viewed from the plan view; and
a conductive pattern that is disposed on a surface of the dielectric member which faces the feed element and that is located at a third position at which the conductive pattern matches the first parasitic element as viewed from the plan view,
wherein the dielectric member is supported by the substrate as a result of the conductive pattern being electrically connected to the first parasitic element.
