The antenna device disclosed includes an insulating antenna case, an antenna base, an umbrella-type element, an amplifier substrate, and a coil. A lower surface of the insulating antenna case is open and a housing space is formed in the insulating antenna case. The antenna case is fitted on the antenna base. The umbrella-type element is provided on the antenna base. The amplifier substrate includes an amplifier which amplifies a signal received by the umbrella-type element, and is disposed on the antenna base. The coil is inserted between an output end of the umbrella-type element and an input end of the amplifier to make the umbrella-type element resonate at a predetermined frequency, and is disposed substantially at a center in a width direction of the umbrella-type element.
