Claim Text:
1. A continuous casting method for continuously casting an ingot made of titanium or a titanium alloy by injecting molten metal having titanium or a titanium alloy melted therein into a bottomless mold and withdrawing the molten metal downward while being solidified, wherein, by controlling temperature of a surface portion of the ingot in a contact region between the mold and the ingot, and/or a passing heat flux from the surface portion of the ingot to the mold in the contact region, thickness of a solidified shell formed by solidifying the molten metal in the contact region is brought into a predetermined range, wherein average values of the temperature Ts of the surface portion of the ingot in the contact region are controlled into the range of 800° C.<T wherein the thickness D of the solidified shell in the contact region is controlled into the range of 0.4 mm<D<4 mm, wherein the contact region is limited to a region near a meniscus.
