Abstract
The objective of the present invention is to provide an information processing device that is operable by a battery and which suppresses the generation of standing waves and has little radiation noise. In the information processing device of the present invention having means for connecting to a battery pack that stores a battery for supplying power to the information processing device, there is one or more capacitive element (for example, a capacitor) in the proximity of the terminals of the positive and negative poles of the battery when the battery pack is connected to the information processing device, and it is possible for at least the terminal of the positive pole of the battery or the terminal of the negative pole of the battery to be connected electrically to the ground of the information processing device by way of this capacitive element.
