摘要 <p>PURPOSE: To reduce the influence of electromagnetic disturbance noise having a possibility that such influence arises on the input and output of a computer and to structurally strengthen the side edges of a multilayered circuit board by providing the computer with a shielding structure. CONSTITUTION: The shielding structural body has two cooperating constituting parts, one of which is a specifically formed grounding surface region existing on the outer layer of a circuit board 20. The other thereof is a specifically formed thin sheet metal member which extends to the circumference of a connector 10 to allow the passage of input/output signals to the circuit in the circuit board 20 and substantially encloses the same. This strip member 111 is formed to have a nearly U-shaped structure and its one flank is placed lower. The base part of the U shape is fixed to the side edge of the circuit board 20 arranged with the grounding surface. The strip member 111 is fixed to the connector conductive shell of the connector, etc. The strip member 111 further structurally reinforces the side edge of the circuit board and strengthens the circuit board 20 against distortion, etc.</p>
