CELL-CONTAINABLE CHIP

Provided is a cell accommodating chip that can identify and isolate a target sample with high accuracy and high efficiency, that can be simply handled, and that allows easy collection without damaging the cell. A cell accommodating chip (60) includes a substrate (60a), a plurality of wells (61), (61), ..., disposed on the upper surface (60b) of the substrate and capable of accommodating a plurality of cells M on one-to-one basis, and a coating layer (62) formed on the inner surface (61a) of each well constituting the plurality of wells and on the upper surface (60b) of the substrate (60a). The surface of the coating layer (62) has low cell adhesion to cells and affinity to a specific binding material that has affinity to a produced substance produced by a cell (M) accommodated in a well (61) or a released substance released by a cell (M) accommodated in a well (61).
