PROBLEM TO BE SOLVED: To provide a position-sensing server capable of ensuring the accuracy of a position sensing even when there is a shield or the like between a position-sensed terminal and a radio LAN access point. SOLUTION: In the radio LAN position-sensing server, the positional information of the position-sensed terminal 130 is corrected on the basis of the information of an IC tag 140 read by an IC tag reader 132 by the position-sensed terminal 130 and the fixed-position informations of a plurality of the IC tags 140, when the fixed-position informations of a plurality of the IC tags 140 fitted within the moving range of the position-sensed terminal 130 are stored, and the positional information of the position-sensed terminal 130 is detected by the communication information of a radio LAN.
