An up-drawing continuous casting method casts a casting having a bent portion. When an angle (θ) (where, 0°≤θ≤90°) between an up-drawing direction of molten metal and an upper surface of a shape determining member is reduced to a first angle, drawing up the molten metal while maintaining the angle (θ) at the first angle, and casting a first casting, and casting a connecting portion adjacent to the cast first casting; interrupting the drawing up of the molten metal, and dipping the connecting portion into the molten metal while passing the connecting portion through the shape determining member, and melting the connecting portion; and setting the angle (θ) to a second angle that is larger than the first angle, restarting the drawing up of the molten metal and casting a second casting adjacent to the first casting.
