摘要
A collecting filter has a filter membrane with a porous structure to filter a nanocarbon material from a dispersion medium containing the nanocarbon material, and a dense film having an opening through which the dispersion medium passes. The opening has a reverse tapered shape in which a first width at an inlet of the dispersion medium opposite to the filter membrane is smaller than a second width at a bottom side adjacent to the filter membrane.
