A reactor cell encloses a reaction tube(2), so that an inner space of the reactor cell is divided into an inner region and an outer region by the reaction tube. A silicon grain layer is formed and a silicon precipitation is generated in the inner region of the inner space of the reactor cell except the outer region. A gas inlet unit is used for supplying a predetermined gas to the silicon grain layer. A product exhaust unit is used for exhausting polycrystalline grains and an exhaust gas from the inner region. An inert gas connection unit is used for keeping the outer region under an inert gas condition. A pressure control unit is used for measuring and controlling the pressures of the inner and outer regions. A pressure difference control unit keeps the difference of pressure between the inner and outer regions in a predetermined range of 0 to 1 bar.
