PROBLEM TO BE SOLVED: To provide a shield structure capable of surly reducing noise emitted from a case. SOLUTION: The shield structure of the case 1 is disclosed for containing a wiring board 30 on which electronic components 31, 32 are mounted. A plurality of connections 13, 23 for interconnecting the interior side of the case 1 and the front side and the rear side of the wiring board 30 are arranged in the case 1, and the connections 13, 23 sandwich the wiring board 30. Through the shield structure above, provision of the connection 23 can feed back a noise current produced from the electronic components to the wiring board 30 within a small loop. The noise radiation of the case 1 acting like an antenna can surely be prevented through the structure capable of suppressing the loop area of the noise current to be small in this way.
