Abstract
A metal pipe includes a slot having a predetermined length in a longitudinal direction of the metal pipe and a wireless tag that is placed inside the metal pipe and includes a power feeding unit to feed electric power to the slot and an IC chip connected to the power feeding unit, thereby functioning as an antenna of the wireless tag. The metal pipe is thus managed by the wireless tag.
