The present invention provides a method of producing an osteoblast construct from human iPS cells, the method including the steps of: (1) inducing formation of an embryoid body by subjecting undifferentiated human iPS cells to non-adherent culture; (2) inducing differentiation of the human iPS cells into mesodermal cells by subjecting the embryoid body of the human iPS cells obtained in the step (1) to non-adherent culture; and (3) inducing differentiation into osteoblasts by subjecting the mesodermal cells of the human iPS cells obtained in the step (2) to non-adherent culture.
