A somatic cell production system comprising a preintroduction cell solution-feeding channel 20 through which a preintroduction cell-containing solution passes, a factor introducing device 30 that is connected to the preintroduction cell solution-feeding channel 20 and introduces a somatic cell inducing factor into preintroduction cells to prepare inducing factor-introduced cells, and a cell preparation device 40 in which the inducing factor-introduced cells are cultured to prepare somatic cells.
