To provide a method of manufacturing a substrate which can omit a process step of slicing from an ingot, and also provide a solar battery which is high in mass productivity, inexpensive, and good in quality.
This method of manufacturing the substrate consists of a process step of forming a casting mold having a groove in a perpendicular direction by mating a plurality of planar members in parallel, a process step of injecting raw material silicon into the groove of this casing mold, a process step of filling the groove by maintaining the casting mold at a temperature higher than the melting point of the silicon and melting and raw material silicon, a process step of forming the planar silicon by solidifying the molten raw material silicon, and a process step of separating the planar silicon from the casting mold by returning the casting mold to a plurality of the planar members.
