In the present invention, a layout of a sensing means is provided in an electronic apparatus comprising such sensing means by which it is possible to substitute the functions of a plurality of sensing devices. An imaging device (100) is provided which includes: a TFT display unit (103) that is movable relative to a body section of the electronic apparatus; an EVF unit (202); and a millimeter wave radar device (309) that enables the simultaneous sensing of the orientation of the TFT display unit (103) and eye contact with the EVF unit (202) by radio wave irradiation. The millimeter wave radar device (309) is arranged at a position and an orientation that are based on the directivity angle, the arrangement information of the TFT display unit (103), the sensing amount of the TFT display unit (103) for orientation sensing, and information on the eye point related to the EVF unit (202).
