1. A cell evaluation method comprising: a labeling step of labeling at least some of cells constituting a cell clump with at least one chemical substance that produces fluorescence or luminescence; an image-capturing step of acquiring a plurality of slice images of the cells that are labeled in the labeling step, for at least part of the cell clump; an evaluating step of evaluating the characteristics of the cells on the basis of the plurality of slice images acquired in the image-capturing step; a 3D-image creating step of creating a 3D image of at least part of the cell clump by subjecting the plurality of slice images acquired in the image-capturing step to image processing; a center-of-gravity determining step of determining a center-of-gravity position of the cell clump from the 3D image of the cell clump created in the 3D-image creating step; and an organizing step of organizing evaluation results obtained in the evaluating step, with respect to the distance from the center-of-gravity position determined in the center-of-gravity determining step.
