To provide information on erecting angle and difference from erecting standard for each member.

This member erecting method comprises a step for mounting a plurality of radio IC tags 200 having memories 202 in which member IDs are stored and antennas 203 for acquiring measurement information 20 from an artificial satellite 10 along the erecting axis 110 of the member 100 apart from each other, a step for receiving measurement information 25 for each member ID by the radio IC tags 200 in a radio IC tag reader 300, and a step for calculating the erecting angle for each member 100 based on the plurality of measurement information for each member ID received and outputting the information on the erecting angle to output interfaces 400, 410, and 500.
