CELL CAPTURING APPARATUS, CELL CAPTURING DEVICE PROVIDED WITH PRE-PROCESSING PART, AND PRE-PROCESSING PART

By providing a pre-processing unit on a processing liquid channel included in a cell capturing apparatus, air bubbles accumulate in an introduction region inside of the pre-processing unit and thus the air bubbles are removed while a processing liquid moves through the introduction region and a discharge region, even when the air bubbles are contained in the processing liquid. By providing a foreign matter removal filter, at least a part of foreign matters (foreign matters that cannot pass through through-holes) contained in the processing liquid can be captured and thus the processing liquid from which the foreign matters are removed can be supplied to a cell capturing device at the subsequent stage.
