A mobile telephone device includes a display casing (1) having display panels (10A, 10B) and a television antenna unit (4), an operation casing (2) having an operation unit (20) and a mobile telephone device antenna unit (5), and a hinge unit (3) for rotatably connecting the display casing (1) to the operation casing (2). The television antenna unit (4) is provided at the end of the display casing (1) opposite the end having the hinge unit (3). The mobile telephone device antenna unit (5) is provided at the end of the operation casing (2) on the hinge unit (3) side. Therefore, the antennas are always separated by the length of the display casing (1). In addition, a ground electrode is formed so as to continuously extend on the display casing (1) and the operation casing (2). One end of the television antenna unit (4) electrically communicates with this ground terminal. Thus, the ground electrode having the length corresponding to the television antenna unit (4) can be provided.
