To provide a wall-mounted storing device which makes a lighting unit inconspicuous while sufficiently securing storage space.

The frame of the wall-mounted storing device, which comprises two opposed side panels, a top and a base panel, is arranged on the wall surface, and the interior of the frame is made storage space. Then an opening is provided to the storage space side of the top, and the lighting unit is inserted from the storage space side. Thus, the lighting unit is stored at the upper location of the inside of the opening of the top, and the frame is arranged in the opening which is provided on the wall surface. Then an opening is provided on the storage space side by forming a through hole on the top, and the through hole penetrates the top in the width direction of the top. Then the lighting unit is stored on the back side of the wall, thus the lighting unit of the wall-mounted storing device is made inconspicuous while sufficiently securing the storing space.
