摘要

A second ground plane ( 18 ); has one end opposite to a connector ( 14 ), which end is connected to a first ground plane ( 17 ) by resistor connection element ( 41 ). Accordingly, it is possible to lower Q of resonance of the ground structure by the resistor connection element ( 41 ) and to prevent generation of an intense electromagnetic field attributed to an electromagnetic field of a data processing circuit. Especially when the resistor connection element ( 41 ) has a resistance value identical to a characteristic impedance of the ground structure, the ground structure is terminated in a matched way and it is possible to assure prevention of generation of an electromagnetic field attributed to resonance.
