Abstract: A method of the invention is a method of processing a wiring substrate that includes a configuration in which conductors locally disposed on a substrate are coated with resin having inorganic members that form a filler and are dispersed in an organic member, the method including: removing the organic member from a surface layer side of the resin by use of an ashing method; and removing, by use of a wet cleaning method, the inorganic members remaining the surface layer side of the resin from which the organic member is removed.
