An imaging apparatus includes a housing having an opening, a camera unit including a lens and an imaging device, disposed inside the housing, and configured to image an external object through the opening, a telecommunication member disposed inside the housing and configured to connect a control substrate controlling the camera unit to an imaging device substrate on which at least the imaging device of the camera unit is mounted, and a communication antenna at least partially disposed in a gap between an inner edge of the opening and the camera unit as viewed in an optical axis direction of the camera unit at a position substantially symmetrical to the telecommunication member across the lens.
