Apparatus for sorting cells and cell alignment substrate of the same

An apparatus for sorting cells, comprising:

• a cell alignment portion applying a process to a cell-suspending fluid in which a great number of cells are suspended and arraying the cells with a spacing between each cell;
• a cell information detecting portion applying a detecting process to the cells arrayed by the cell alignment portion and detecting information on the cells;
• a cell sorting portion for sorting the cells based upon the information detected by the cell information detecting portion;
• a first passage included in the cell alignment portion so as to let the cell-suspending fluid flow;
• and
• a second passage included in the cell alignment portion, intersecting with the first passage so as to communicate with the first passage, letting a splitting fluid flow so as to split the flow of the cell-suspending fluid in the first passage, and forming a great number of small cell-containing liquid drops.
