A control method for a target supply device includes melting a target material by heating the target material within a target generator using a heating unit, pushing out the target material from a nozzle hole in a nozzle by pressurizing the interior of the target generator using a pressure control unit, determining whether or not the size of an adhering area of the target material that forms when the target material is pushed out from the nozzle hole and adheres to a leading end of the nozzle has reached a set size that covers the entire nozzle hole, stopping the pressurization of the interior of the target generator by the pressure control unit when the size of the adhering area has reached the set size, and hardening the target material in the target generator and the adhering area by stopping the heating of the target material by the heating unit. |
