Abstract
A sheet of glass (rear glass) is provided with a radiation conductor. An electronic circuit unit includes a base plate soldered on the radiation conductor so as to be 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 base plate has a narrow section that connects a soldering section and other sections of the base plate. The soldering section is provided with a protrusion that abuts on the radiation conductor such that a solder-accumulation space is formed around the protrusion. Furthermore, the base plate is provided with a plurality of height-adjustment portions disposed at different positions and distant from the soldering section. Each height-adjustment portion has substantially the same dimension as the protrusion.
