PROBLEM TO BE SOLVED: To provide an imaging device with built-in antenna for effectively irradiating and entering radio waves therein even though the device is in a conductive housing, and can effectively irradiate and enter the radio waves from any direction independent upon ways of placing and holding of the device. SOLUTION: The device is equipped with a plurality of openings with a fixed length and a slit-shape at a part of the conductive housing, and disposes the openings with a slit structure longitudinally and sidlingly in response to main polarized waves of antennas disposed at the openings. Each of the disposed antennas is configured in a manner that transmitting power for supplying to each of the antennas of which respective main polarized wave surfaces are different to evenly supply the antennas having different main polarized waves, respectively. Receiving power received from the antennas is received from the antennas having the different polarized waves, respectively, and received by combining the power, respectively.
