Abstract
In an oscillator employing a triplate type stripline, earth (ground) electrodes are formed only on an opposite pair of side surfaces of a substrate in which the stripline is embedded. An oscillation circuit mounted on the substrate is covered with a shielding case and the remaining side surfaces of the substrate, which are provided with no earth electrodes, are covered with shielding plates which are provided on the shielding case. Connecting portions of the shielding case are electrically connected with the earth electrodes by soldering. Thus, the stripline is electromagnetically shielded in a simple manner so that it is possible to easily manufacture an oscillator employing a stripline at a low cost.
