    摘要: An antenna unit has a coaxial cable firmly connected and fixed to an antenna substrate by an easy soldering process and provides freedom in pattern formation and mounting of parts on the antenna substrate. The antenna unit includes an antenna substrate on which an antenna element and antenna circuit parts are mounted, and on which a power supply pattern or a ground pattern is formed. A shield case is attached to the antenna substrate so as to cover the mounted parts. A nearly C-shaped notch is formed on the main surface of the shield case opposed to the antenna substrate to form a tongue piece-shaped hold-solder part. A coaxial cable is connected to a connection part formed on the antenna substrate and led from a lead part formed on a side surface of the shield case.
