An information processing device includes: an information acquisition process control unit for selecting an information piece to be selected and sending an instruction to a communication unit; the communication unit for transmitting an information acquisition request to other information processing device connected via a network, and acquiring information from the other information processing device according to the instruction; and a storage unit storing a display amount information indicating the amount of display information which can be displayed on a display unit at once. The information acquisition process control unit instructs the communication unit to acquire more information than the amount indicated by the display amount information. This realizes an effective information acquisition and appropriate user-friendliness.
