A method of transferring a substrate with a transfer unit including at least one fork having a substrate support portion, and a sensor arm having a sensor mounted thereon, for transferring the substrate between a substrate holding member and a substrate support member, includes the steps of arranging a position detecting plate on a rest portion of the substrate support member, obtaining position information of the position detecting plate by detecting the position of the position detecting plate with respect to the reference position of the transfer unit by the sensor arm, and transferring the substrate by controlling the position of the transfer unit on the basis of the position information.
