<p>PROBLEM TO BE SOLVED: To provide a cell spreading device capable of improving the detectability of target cells and the number of collected target cells by avoiding peel-off and stacking of cells even when one-shot liquid feed, continuous liquid feed, or the like is performed.SOLUTION: The cell spreading device includes a cell spreading area part A of a predetermined shape. When the cell spreading area part A is assumed to include a first region D where a cell suspension flows at an average speed V, second regions C, Cwhere the cell suspension flows at a speed faster than that in the first region D, and third regions E, Ewhere the cell suspension flows at a speed slower than that in the first region D, the depth of a microchamber 36 located in the second regions C, Cis increased and at the same time the depth of a microchamber 36 formed in the third regions E, Eis decreased. Thus, the flow speeds of the cell suspension in the first, second, and third regions are approximated to each other.</p> |
