The problem to be solved by the present invention is to prevent interruption of a cellulose acetate fiber during spinning of the cellulose acetate fiber thereby enhancing production efficiency of a cellulose acetate band. The cellulose acetate band according to an embodiment of the present invention is formed from cellulose acetate fibers, a total denier thereof is set to a value in a range from 8000 to 44000, a content of titanium oxide is set to a value in a range from 0 wt.% to 0.01 wt.%, and a content of a lubricant in the band measured by a diethyl ether extraction method is set to a value in a range greater than 5 mg but 65 mg or less per 1 m.
