摘要

A direction estimating section (11) estimates the incoming direction of a radio wave from an RFID tag (1) in each of antennas. A position calculating section (14) calculates the position of the RFID tag on the basis of the incoming direction of the radio wave estimated in the direction estimating section (11).
