Along with this, peripheral extension devices called docking stations, port replicators, etc. are increasingly used to satisfy both portability and expandability.

At this time, it is required to further reduce the high-frequency impedance between the reference potential surface of the information processing apparatus main body and the reference potential surface of the peripheral extension device in order to stably operate the device and reduce unnecessary radiation.

The connection between the reference potential plane of the information processing apparatus main body and the reference potential plane of the peripheral extension device will be described below with reference to FIGS. 5 and 6.

Reference numeral 15 denotes a signal connector on the main body side, 15 denotes a signal connector on the peripheral extension device side, and 20 denotes an electric circuit board inside a housing 22 of the peripheral extension device. The information processing device is composed of the information processing device main body and the peripheral extension device.
