Abstract
Provided are a desmearing method and a desmearing device which are able to reliably remove a smear derived from any of an inorganic substance and an organic substance, and eliminate the need to use a chemical that requires a waste liquid treatment. The desmearing method of the present invention is directed to a desmearing method for a wiring substrate material that is a laminated body of insulating layers made from resin containing a filler and a conductive layer, and includes an ultraviolet irradiation treatment step for irradiating the wiring substrate material with ultraviolet beams with a wavelength of 220 nm or less, and a physical vibration treatment step for applying physical vibrations to the wiring substrate material which has undergone the ultraviolet irradiation treatment step.
