Abstract
A telecommunication unit which ensures high reliability of electric connection with a simple structure and enables satisfactory communication between an apparatus main body of an image pickup apparatus and an interchangeable lens. A first electric connecting unit has contact portions that are electrically connected to the interchangeable lens when the interchangeable lens is mounted on the lens adapter. A second electric connecting unit has contact portions that are electrically connected to the apparatus main body when the lens adapter is fixed to the apparatus main body. The contact portions of the first electric connecting unit are arranged in the form of an arc with an optical axis of the interchangeable lens at its center. The contact portions of the second electric connecting unit are arranged in a linear fashion in a width direction of the apparatus main body perpendicular to the optical axis of the interchangeable lens.
