A wireless communication system includes: wireless IC chips used for identifying objects; a transceiver for transmitting and receiving information to/from the wireless IC chips by radio waves; and a radio wave direction unit for directing the traveling directions of the radio waves from the transceiver toward the wireless IC chips. The radio wave direction unit is arranged such that the radio wave reflecting surface can be developed to face a collection space where the wireless IC chips are collected. A part of the radio waves radiated from the transceiver travels stereoscopically toward the collection space S by an action of the radio wave reflecting surface.
