Abstract: A single or a plurality of semiconductor chips or thin film elements which are bare or passivated to a minimum extent are housed in an enclosure member formed by drawing into the shape of a tray from a laminate consisting of an insulation layer and a first and second conductive layers formed on opposite sides, respectively, of the insulation layer. The enclosure member has a concavity having a substantially flat bottom and circumferential edge. There are provided on the inner surface of the concavity as extended to the circumferential edge, wiring conductors which are destined for connecting the terminal electrodes of the semiconductor chip or the like to the terminal electrodes corresponding to electronic parts on a circuit board, while the outer surface of the concavity is held at the ground potential to form an electromagnetic shield. The semiconductor chip or the like is connected to one end of the wiring conductor by the wire bonding process and resin-molded in the concavity.
