A metal filter includes a plurality of through holes. An opening shape of each of the plurality of through holes is a rectangle or rounded-rectangle and a length of a short side of the rectangle or a rounded rectangle is 5 to 15 &#x3bc;m. A method for concentrating cancer cells using the metal filter includes separating cancer cells from blood and blood cell constituents by passing blood, red blood cells, white blood cells, and platelets through the plurality of through holes while capturing cancer cells to concentrate the cancer cells.

Metal filter and method for concentrating cancer cells

Provided are a cancer cell-trapping metal filter which has a high opening ratio, a cancer cell-trapping metal filter sheet, a cancer cell-trapping device using the cancer cell-trapping filter, and manufacturing methods therefor. According to a cancer cell-trapping metal filter, openings of connected through-holesthat are formed in a metal sheethave a wave shape, and thus it is possible to extract a CTC from other components by utilizing a hole diameter on a short-side side of the openings, and it is possible to make the connected through-holes be closer to each other due to the wave shape while maintaining a CTC trapping ability. Accordingly, it is possible to further improve the opening ratio in the cancer cell-trapping metal filter
