Abstract
Arnold () includes a recessed portion () for receiving a melt (). The recessed portion () is constituted by an inner wall surface () for converting the melt () into a solidified portion when the inner wall surface () contacts the melt (), and opens in a withdrawal direction (D) of the solidified portion. A curved line formed by a first contour () and a second contour () has a cusp at a position of start points (and). The distance between the first contour () and the second contour () in a width direction (D) increases continuously from an upstream side to a downstream side of the withdrawal direction (D). The shape of the inner wall surface () of the recessed portion () is determined so that a cast rod () can be rotationally displaced clockwise or counterclockwise about an axis passing through a first end point () or a second end point () and perpendicular to a section of the mold
