Abstract
A cell capturing filter, in which cells or particles having a predetermined size or greater in a sample may be easily captured, and clogging of a flow passage due to the captured cells or particles may be prevented, and stresses acting on the captured cells or particles may be reduced, having a first surface and a second substrate having a second surface that is bonded to the first surface, wherein the first substrate may include a flow passage formed in the first surface of the first substrate so that a sample flows in the flow passage, and a barrier that protrudes across the flow passage, and the second substrate may include a fine groove formed in an area on the second surface corresponding to the barrier, and a gap may exist between a surface of the barrier and the fine groove.
