Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an electret processed article, by which the electret processed article having a high quality and a high performance can be produced at a low cost. SOLUTION: This method for producing the electret processed article is characterized by spraying a polar organic solvent L on a non-conductive sheet S to impregnate the non-conductive sheet S with the solvent, and then drying the treated non-conductive sheet S to produce the electret sheet.
