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.
