Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and an apparatus for regenerating nozzles of an inkjet head which enable nozzle clogging to be regenerated in a short time simply while a solvent shock because of a coating liquid and a solvent for cleaning is avoided. SOLUTION: In the method for regenerating nozzles of the inkjet head, a defective ejection part is regenerated by solving clogging of a blocked nozzle hole by applying a preliminarily set load using a needle for regeneration 5 which has a diameter smaller than or the same size as a diameter of the nozzle hole turned ejection defective due to clogging by foreign substances such as dried ink at a nozzle part which ejects the ink of the inkjet head 1. A needle for cleaning 6 is installed, and the periphery and inside of the nozzle hole is cleaned by a cleaning liquid ejected from a tip of the needle for cleaning 6 after the nozzle hole is regenerated by the needle for regeneration 5.
