Summary:A manufacturing method of an electret processed product, comprising the steps of allowing a section nozzle ( 22 ) to come into contact with a nonconductive fiber sheet (S) so as to cross in the lateral direction of the sheet while running the sheet, allowing the surface of the sheet on the opposite side of the contact portion to come into contact with or to immerse into a water surface, sucking water from the suction nozzle ( 22 ) so that the water can be passed through the sheet in the thickness direction of the sheet to penetrate the water into the nonconductive fiber sheet (S), and drying the nonconductive fiber sheet (S), whereby a high quality and high performance electret processed product can be manufactured at a low cost.
