By doing this, the installation work is completed by mounting the display 3 on a printed wiring board to be provided in the case 2. The display 3 is installed in the case 2 so as to be placed at an position and in a direction easily visible from an occupant in a cabin, and thus, excellent antenna sensitivity to the device of a communication target can be obtained.
