[Problem] To provide: a method that is capable of more easily producing a three-dimensional cell structure than conventional methods； and a support used for the same. [Solution] This support 1 includes frame bodies 10A, 10B, 10C, 10D on four sides； and X- and Y-direction string members 20 extending between the frame bodies 10. The string members 20 form, in the support 1, a plurality of meshed rectangular spaces. In the meshed spaces of the support 1, cell aggregates are dispensed from a dispenser, and a plurality of such supports 1 are stacked. Finally, the support 1 and the string members 20 are removed from the three-dimensional cell structure formed by the adhesion and fusion of the cell aggregates.
