An adhesive sheet 301A having a predetermined form is laminated onto a long release sheet 2A, and a protective member 5A which is thicker than the adhesive sheet 301A is provided in a position so as not to overlap the adhesive sheet 301A when a laminate sheet 1A is wound into a roll. Charged spots are formed by a converging ion beam or the like on a substrate having an insulating property or the like, and micro-bodies having a size of 200 microns or less are attracted and stuck to the charged spots. The front sides, the back side and the leg encircling regions are formed from one piece, and the front sides and the leg encircling regions, respectively, are openableclosable. The cutter sleeve has an outer surface and a hollow construction, and is preferably appointed for a single use. The flow through the sample separation media is unidirectional. A product of the reaction of the polymer and the halogenating agent, in conjunction with the surfactant when present, is capable of causing the separation of at least a portion of the oil from the solid material.
