PROBLEM TO BE SOLVED: To stabilize electric contact between carriers while electromagnetic shield performance is improved by preventing poor electric contact at a carrier's conductive interconnection part which functions as a ground of an electric circuit. SOLUTION: Guide channels 8 and 9 are formed at interconnection surfaces 2a and 3a of conductive carriers 2 and 3 which are provided in a case, adjoining each other, and a conductive member 10 is inserted in the guide channels 8 and 9 so that the carriers 2 and 3 are electrically connected each other. Guide channels 14 and 15 are formed at joint surfaces 12 and 13 of the case 1 and a lid 11, and a conductive member 16 is inserted in the guide channels 14 and 15 so that the case 1 and the lid 11 are electrically connected.
