摘要： PROBLEM TO BE SOLVED: To provide a casting apparatus for silicon, which has high productivity, and can reduce a difference in height between a center part and an edge of an ingot, and to provide a casting method of silicon.SOLUTION: A casting apparatus for silicon includes: a casting mold having multiple of internal surfaces and an opening at an upper part surrounded by the multiple of the internal surfaces; and one or more heat radiation members which is disposed in the peripheral part of the opening, and radiates radiation heat to a ridge line part between the adjacent internal surfaces. A casting method for silicon includes steps of: preparing a casting apparatus for silicon that includes a casting mold having multiple of internal surfaces and an opening at an upper part surrounded by the multiple of the internal surfaces, and one or more heat radiation members which is disposed in the peripheral part of the opening, and radiates radiation heat to a ridge line part between the adjacent internal surfaces; providing a status with a silicon melt in the casting mold; and solidifying the melt while heat from the outside is absorbed by the heat radiation members and the radiation heat from the heat radiation members is given to the surface of the melt positioned in the ridge line part.
