A teaching method according to an embodiment is for a transfer device including a substrate holding unit including a suction port for holding a substrate by applying suction, an actuation mechanism for moving the substrate holding unit, and a pressure detecting unit for detecting a pressure in a suction path communicating with the suction port. The method includes: moving the substrate holding unit under the substrate; moving the substrate holding unit upward toward the substrate, while applying suction to the suction path and detecting the pressure in the suction path; determining whether or not the substrate holding unit has touched the substrate, based on the pressure in the suction path; and storing, as a standard position, a position of the substrate holding unit at a time of determining that the substrate holding unit has touched the substrate.
