NOVELTY - The method involves discharging silicon melt solution (4) to a granular form, where the discharge rate is measured from the discharge amount of melt solution per unit time. The supply weight of silicon raw material is controlled so that melting rate of raw material supplied to crucible (1) turns into more than the discharge rate, by a supply weight control unit (21).    USE - Manufacturing method of crystalline silicon particle used for solar cell.    ADVANTAGE - The supply of silicon raw material can be discharged continuously, without interrupting the discharge of silicon melt solution from the nozzle of crucible. Therefore the reproducibility is good at low cost, while obtaining high productivity of crystalline-silicon particle. The continuity of manufacturing process is improved. As the melting rate is controlled in a specific manner, the rapid temperature fall of silicon melt solution can be suppressed. The discharge amount of silicon melt solution from the crucible can be measured correctly, by using the weigher. As the heat-insulation material is provided, the failure of weigher due to heat generation can be prevented effectively. As the container is made of quartz, the container is inexpensive, which reduces the manufacturing cost.    DETAILED DESCRIPTION - The total discharge weight of silicon melt solution discharged from the crucible through a nozzle (1a) is set between the residual weights in the time of last supply of melt solution in the crucible, after supplying the silicon raw material to the crucible. The discharge weight of silicon melt solution is measured by using a weigher installed in the container made of quartz. A heat insulation material is installed between container and weigher. A forced-cooling material is provided between the heat insulation material and the weigher. A pipe (2) is installed for discharging the melt solution of granular form from the crucible, having smaller accommodation opening than that of container. An INDEPENDENT CLAIM is included for manufacturing apparatus of crystalline silicon particle.
