An antenna device receives radio waves, excites received signals corresponding to the received radio waves, and transmits the received signals to a radio wave-using operation module block including received signal using elements. The radio wave-using operation module block includes a pair of flat surfaces facing in opposite directions and an outer circumferential surface connecting the peripheral edges of the flat surfaces to each other. The antenna device includes an elongate antenna core member which extends along the outer circumferential surface of the radio wave-using operation module block, and an antenna coil which is wound around at lease a part of the antenna core member in the longitudinal direction thereof and which is connected to the received signal using elements of the radio wave-using operation module block.
