Title:
濾過フィルタ及び濾過方法
Document Type and Number:
Japanese Patent JP7021708
Kind Code:
B2
Abstract:
Provided is a filtration filter that helps keep a filtration target from drying out. A filtration filter according to the present invention has a first principal surface, a second principal surface opposite the first principal surface, and a filter substrate defining through-holes extending from the first principal surface to the second principal surface. The filter substrate is a site on which a filtration target contained in a liquid is to be captured. When a cross section of the filtration filter is taken in a direction from the first principal surface to the second principal surface and along a line passing through adjacent ones of the through-holes, the filter substrate between two adjacent ones of the through-holes has a pair of projections. Projections of the pair of projections are provided on corresponding end portions on opposite sides in a width direction of the filter substrate and protrude from the first principal surface. The first principal surface and the pair of projections define a reservoir part in which some of the liquid is to be retained.
