PROBLEM TO BE SOLVED: To prevent ground structure, with which first and second ground planes are connected by a connector, from generating strong electromagnetic fields, with which radio communication is interfered. SOLUTION: Since the edge of a second ground plane 15 opposite to a connector 14 is connected to a first ground plane 11 by a resistance connecting means 41, Q value of resonance in the ground structure can be lowered by the resistance connecting means 41 and the strong electromagnetic field can be prevented from being generated by the electromagnetic field of a data processing circuit. Especially, when the resistance value of the resistance connecting means 41 is identical to the characteristic impedance of the ground structure, since the ground structure is matched and terminated, the electromagnetic field can be surely prevented from being generated by resonance.
