An upward-drawing continuous casting method according to one embodiment of the present invention is provided with: a step in which a molten metal (M1) held in a holding furnace (101) is passed through a shape-regulation member (102) and drawn upward, said shape-regulation member (102) regulating the cross-sectional shape of a casting (M3) to be cast; a step in which a pair of rod-shaped members (110), while in a state of being in contact with each other, is inserted into a molten metal (M2) being drawn upward while being passed through the shape-regulation member (102), to determine an upper end of an opening (50) to be formed in the casting (M3); a step in which the pair of rod-shaped members (110) inserted in the molten metal (M2) is separated; a step in which the separated pair of rod-shaped members (110) is brought into contact with each other again; and a step in which the pair of rod-shaped members (110), having been brought into contact with each other again, and while in a state of still being inserted in the molten metal (M2), is lifted further towards an upper side than a solidification interface (SIF) to determine a lower end of the opening (50). |
