PROBLEM TO BE SOLVED: To provide an imaging device having a built-in radio communication unit without increasing the size of the device and maintaining a stable radio communication state.SOLUTION: The imaging device includes a pentaprism 51 that guides incident light to an eyepiece optical system and a plurality of exterior members. In an imaging luminous flux incident from an imaging optical system, the light reflected on a revolving mirror 52m is further reflected on a reflection surface of the pentaprism 51 to reach an eyepiece lens. A radio board 41 mounting an antenna part 42 is disposed between the pentaprism 51 and a front exterior cover 102. A board fixing member 44 fixes the radio board 41; and a ground part of the radio board 41 is connected to the board fixing member 44 at a position opposite to the antenna part 42 via the optical axis of the eyepiece optical system. The board fixing member 44 is mounted on a pentaprism fixing member 57 and electrically connected to the ground part of the imaging device. In the front exterior cover 102, an electric resistance value in a region opposite to the antenna part 42 is relatively higher than in the periphery. |
