Abstract
In a surface-mounting-type electronic-circuit unit, circuit elements, including capacitors, resistors, and inductive devices, and electrically conductive patterns connected to the circuit elements are formed on an alumina board as thin films. Semiconductor bare chips for a diode and a transistor are wire-bonded to connection lands in electrically conductive patterns. And end-face electrodes connected to grounding electrodes, input electrodes, and output electrodes of electrically conductive patterns are formed at side faces of the alumina board.
