PROBLEM TO BE SOLVED: To prevent electromagnetic waves from entering each input-output terminal by providing an electromagnetic shielding member for input-output terminal on the whose surroundings of a plurality of input-output terminals for connecting electronic components to a mounting substrate. SOLUTION: An electronic component is covered with a metallic case 4 of an electronic shielding member for electronic part and shielded from electromagnetic waves. Then, a high height dam 5, an electromagnetic shielding member for input-output terminal for absorbing external electromagnetic waves, is arranged on the whole surroundings of a plurality of I/O pins. The high height dam 5 which is made of a conductive member, is positioned in the bottom side of an electronic part to provide it so as to be bonded on a mounting substrate 2 in the condition of closely contacting with the bottom of the electronic part. Furthermore, the I/O pins 3 are insulated from the metallic case 4 by a insulation member 7, and is bonded with a pad 6 for input-output terminal provided on the side of the mounting substrate 2 by a solder 8. |
