A board having multi-directional casters capable of self-advancing by rolling is provided to automatically move forward without the artificial driving force, by applying rolling on a board body by moving the center of gravity or dispersing power. The board(10) having multi-directional casters capable of self-advancing by rolling is composed of a pair of caster units(230) coming into contact with the ground and independently and freely steering the direction and a steering unit(210) rotatably installed at the underside of the board. The caster units are combined to both sides of the steering unit correspondently to each other. When repeated rolling motions are applied to the board by displacement of force or weight, a pair of caster units automatically move forward with crossing each other within the limited angle, centering on the steering unit.
