Abstract
Provided is a transport device in which reliability is increased by suppressing deterioration of the transport surface and transport efficiency is increased by suppressing electrical current loss. A transport devicecomprising a transported body having either a permanent magnetor a magnetic body, and an electromagnet unit in which coilsare wound around teethcomprising magnetic bodies, and having recesses on surfaces of the teethfacing the transported body. Specifically, the surfaces of the teethfacing the transported body have at least two surfaces (first facing surface, second facing surface, etc.) which have different distances to the transported body.
