The present invention addresses the problem of providing a method for obtaining Schwann cells directly (by direct reprogramming) without passing through pluripotent stem cells, such as ES cells or iPS cells. As a means for solving this problem, the present invention provides a method for preparing Schwann cells that includes a step of introducing into somatic cells of a mammal at least one gene selected from the group consisting of SOX10 genes and KROX20 genes, or an expression product thereof.
