PROBLEM TO BE SOLVED: To provide a shield structure of an electronic circuit by which a reliable electromagnetic wave shield capability can be obtained and the size and weight of the shield structure can be reduced, by providing a sheet exhibiting conductivity as a shield body for covering a board. SOLUTION: A shield sheet 20 exhibiting conductivity is provided approximately in parallel to a circuit board 10, and the circuit board 10 and the shield sheet 20 are electrically connected by a connector 30. Insulating sheets 40 are further provided between the electronic circuit of the circuit board 10 and the shield sheet 20, in such a way that the electronic circuit of the circuit board 10 is covered with the shield sheet 20 and the insulating sheet 40. In this way, leakage of electromagnetic wave from the electronic circuit of the circuit board 10 to the outside and entry of electromagnetic wave from outside into the electronic circuit is prevented by the shield sheet 20. The electromagnetic wave shield can be reliably performed and the dimension of the shield structure can be reduced. COPYRIGHT: (C)2003,JPO
