发明名称 ELECTRONIC EQUIPMENT HAVING CASE BODY CONTAINING CIRCUIT BOARD
摘要 <p>PROBLEM TO BE SOLVED: To provide an electronic equipment capable of enhancing the shield effect of electromagnetic noise, while sufficiently securing the contact area between the ground layer of a circuit board and a case body. SOLUTION: This electronic equipment is provided with a circuit board 40 having an insulating layer 44, signal wiring layers 45a, 45b and a ground layer 46, arranged inside the insulating layer 44 as well as a conductive case body 24 containing the circuit board 40, also having a wall surface opposite to the circuit board 40. The circuit board 40 has a recessed part 52 passing through the circuit board 40 in the thickness direction thereof. A ground layer is exposed in the inner surface of this recession, while a conductive layer 54 electrically connected to the ground layer is formed on the outer periphery of the circuit board, including this recessed part. Furthermore, a conductive projection 56 to be inserted into the recession 52 is formed on the wall surface of the case body 24, while the projection 56 is in contact with the conductive layer of the circuit board 40.</p>
