An elastic band may include an elastic weaving body, and a three-dimensional protruding surface is knitted on a front surface of the elastic weaving body while a flat plush surface is knitted on a rear surface thereof. The three-dimensional protruding surface comprises a plurality protruding portions separated with the same interval. When the elastic band is in use, the protruding portions not only can improve the friction coefficient of the surface so as to avoid the elastic band from loosen, but also can be used as ribs on the elastic weaving body to prevent the elastic band from being folded and to keep the elastic band smooth. Also, the three-dimensional protruding surface and the flat plush surface can provide extra soft touch for skin and have the effect of reducing pressure, which greatly improves comfort to wear.
