ABSTRACT:
A sheet of glass (rear glass) is provided with a radiation conductor and a ground conductor. An electronic circuit unit includes a base plate fixed on the sheet of glass; a frame body which houses a circuit substrate and is screwed on the base plate; and a cover for covering the frame body. The circuit substrate has a component-holding surface and a radio-wave reflective surface at opposite surfaces of the circuit substrate, the radio-wave reflective surface facing the radiation conductor. A section of the frame body proximate the sheet of glass is provided with an engagement portion that fits in an opening of the base plate; and stoppers placed on sections of the base plate that are adjacent to the opening. An amount of insertion of the engagement portion with respect to the opening is set within a thickness of the base plate.
