Abstract: The object of the present invention is to economically produce a high-purity sponge titanium material containing fewer amounts of oxygen and metal elements. To realize this object the vacuum separation time t in a vacuum separation step is t=to+(15˜35) hour where the time t is the vacuum separation time in a vacuum separation step and to is defined as the time from the start of the vacuum separation till the time when the temperature of the central part of the material in a reaction vessel reaches a stable temperature. At and near the central part of the material where the amounts of metal elements are small, the specific area measured by the BET method is 0.05 m2/g or less. Thus, even if the cutting and crushing of the material are performed in the atmosphere, the amount of oxygen in the cut and crushed material can be suppressed to a low level.
