Abstract: A carrier measuring device includes a rotary table, a table drive motor, an upper thickness sensor, a lower thickness sensor and a slide unit. The rotary table includes a carrier receiver configured to horizontally house a carrier formed with a hole in which a semiconductor wafer is held, the hole being eccentric with respect to the carrier.

The slide unit slides the rotary table in a horizontal direction. The carrier receiver is formed to be capable of housing the carrier in a manner that a center of the hole coincides with a center of the rotary table.
