1. A conveying device that conveys a conveyance container including a magnet or a magnetic body to a target position along a conveyance path, comprising:
a conveyance surface configured by arranging a plurality of magnetic poles including a core and a coil, and having a conveyance path;
a drive unit for supplying a current to the coil; and
a position detection unit for performing a process of estimating the position of the conveyance container, wherein
the position detection unit performs:
a process of exciting a first magnetic pole selected to detect the position of the conveyance container, and applying a voltage to at least one second magnetic pole that is a peripheral magnetic pole within a predetermined range from the first magnetic pole and is different from the first magnetic pole in a direction in which the polarity becomes opposite to the exciting current of the first magnetic pole, and
a process of estimating the position of the conveyance container based on a current value of the first magnetic pole.
