Abstract
An energy collection device that increases output power to be collected is provided. Provided is an energy collection device that includes: an antenna unit having a dipole structure, the antenna unit including a first antenna element that is in contact with an industrial product metal portion or a human body and functions as an antenna, and a second antenna element including a conductor, the antenna unit receiving electric field energy of a radio wave and a quasi-electrostatic field existing in space; a rectifier circuit provided with a switching element that rectifies alternating current (AC) energy output from the antenna unit; and a power storage capacitor configured to store charge output from the rectifier circuit, in which the power storage capacitor has a capacitance value of at least 1 μF or more in order to receive power in a low frequency band.
