Abstract: An antenna device includes a wireless module, a module substrate, and a metal plate. The wireless module includes an antenna element that operates in a millimeter wave band. The module substrate is a multi-layer wiring module substrate on which the wireless module is mounted. The metal plate has a length of 1/10 or more of an operation wavelength and is positioned in a vertical direction relative to a plane surface of the antenna element and in a predetermined distance from the antenna element.
