An object of the present invention is to provide a cell structure which can be produced within a short period of time and has a predetermined or larger size, and a method for producing the above-described cell structure. According to the present invention, there is provided a cell structure including: a biocompatible macromolecular block; and two or more kinds of cells, in which a plurality of the biocompatible macromolecular blocks are arranged in gaps between a plurality of the cells, and in which the two or more kinds of cells contain at least one kind of first cell selected from the group consisting of vascular endothelial cells, cardiac muscle cells, pancreatic islet cells, liver cells, epithelial cells, endothelial cells, nerve cells, embryonic stem cells, induced pluripotent stem cells, corneal epithelial cells, and retinal pigment epithelial cells, and at least one kind of second cell selected from the group consisting of mesenchymal cells, stromal cells, fibroblasts, smooth muscle cells, myoblasts, mesenchymal stem cells, adipose-derived stem cells, and umbilical cord-derived stem cells.
