PROBLEM TO BE SOLVED: To provide a casting apparatus for a polycrystalline silicon capable of reducing the production cost by increasing the production amount of silicon ingot in a single casting operation. SOLUTION: In a casting apparatus B for a polycrystalline silicon equipped with a crucible 3 having a cylindrical shape with a bottom for accommodating a silicon solid raw material T1, a heater 6 for melting the silicon solid raw material T1 accommodated in the crucible 3 by heating it, a cooling plate 5 for solidifying while cooling the silicon solid raw material T1 melted by heating with the heater 6 on which the crucible 3 is placed, and a heat insulating member 9 disposed at an outer periphery of the crucible 3, there is provided on the crucible 3 a raw material-loading member 3e that expands the opening part of the upper end 3c side as rising upward.
