Abstract: A filtration filter having a tubular shape, defining a first opening and a second opening facing the first opening, and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction from the first opening of the filtration filter toward the second opening and extends in a second direction along at least a first portion of a circumference of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

Abstract: A filter includes a plurality of first through holes which are periodically formed. At least one of the plurality of first through holes is divided by a plurality of second through holes that are smaller than the first through holes. With such a configuration, the cell aggregate having the desired size can be easily sampled.

Abstract: In a cell-capturing filter including a metal porous membrane, degradation over time is determined earlier. A cell-capturing filter includes a metal porous membrane having a plurality of through-holes that penetrate between two principal surfaces facing each other. The metal porous membrane is made of an alloy of nickel and an element selected from the group consisting of gold, platinum, and palladium, or a metal containing nickel as a main component. A metal containing copper as a main component is attached to a part of either one of the principal surfaces of the metal porous membrane. By checking a state change of the metal containing copper as a main component, degradation over time of the metal porous membrane can be determined earlier.

Abstract: A filtration filter device that enables an object filtered and left on a filtration filter to be more readily observed is provided. The filtration filter device includes a filtration filter that filters an object contained in a fluid, a holding member that holds an outer circumferential portion of the filtration filter, and a tubular member that is removably mounted on the holding member such that a hollow portion that serves as a channel through which the fluid flows faces at least a part of a main surface of the filtration filter.

Abstract: A filtration filter comprises a metallic mesh having a circumferential shape and radially inner and outer portions. The metallic mesh is adapted to filter out a filtration target object contained in a fluid passing through the membrane. First and second frame members hold the outer portion there between so as to create first and second bent sections separated by a transition section extending between the first and second bent sections. The transition section includes at least one streaked projection.

Abstract: A cell filtration filter that includes a metal membrane part that has a first main surface on which the cells are to be captured and a second main surface that opposes the first main surface. The metal membrane part has a plurality of hole edges that define a plurality of first through holes and a support region that is arranged around the hole edges and supports the hole edges. In the support region of the metal membrane part, a plurality of second through holes, which have smaller openings than the first through holes, are arranged so as to surround the hole edges. On the first main surface of the membrane part, the hole edges are raised with respect to the support region.
