Abstract
An antenna device includes an oscillating body capable of oscillating at a predetermined natural frequency, and being displaceable by external magnetic field, and a converter for converting motion of the oscillating body to an electrical signal. When a radio wave signal of a frequency band at which the oscillating body resonates comes, the oscillating body resonates with a magnetic field component of the radio wave signal, and the converter converts the motion to the electrical signal, whereby an electrical signal corresponding to the radio wave signal is outputted.
