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 device includes a container, a channel member, and a filter. The container has a space of variable volume that contains a liquid, the liquid including a target substance to be separated by filtration. The channel member includes a channel and an opening that are defined therein, the opening being provided at a position along the channel in a direction transverse to the direction in which the channel extends. The channel member has an attachment part to which the container is attached and which provides communication between the space in the container and the channel. The filter is attached inside the channel member and positioned at the opening.

Abstract: A filtration filter device that includes a filtration filter that filters an object to be filtered that a fluid contains, and a holding member that holds an outer circumferential portion of the filtration filter. An annular projecting portion that projects in a thickness direction of the holding member and that defines a channel through which the fluid flows is formed on one main surface of the holding member. A recessed portion that is recessed in the thickness direction of the holding member and that has an inner diameter larger than an inner diameter of the projecting portion is formed on the other main surface of the holding member. The filtration filter is disposed inside the projecting portion of the holding member.
