PROBLEM TO BE SOLVED: To provide a structure by which increase in electromagnetic noise because of an opposed antenna constituted by a housing of an electronic device and a metal surface of an extension unit is prevented. SOLUTION: The housing 10 of the electronic device in which a power supply unit 14 is incorporated has several openings 12a-12c opposed to the metal surface 21 of the extension unit 20. Under these conditions, an electrical connection means 30 composed of a conductive member 31 and a leaf spring 32 is arranged in a position adjacent to the peripheral border of the opening 12c, in order to prevent an electromagnetic wave leaking from the opening 12c having the largest area as indicated by an arrow R<SB>1</SB>from being amplified between the metal surface 11 of the housing 10 of the electronic device and the metal surface 21 of the extension device 20.
