An alternatingly driven board is provided to be driven by using both feet alternatingly, to be driven easily and to be easily applied to an ordinary life. In an alternatingly driven board, one or more directional casters(200) are mounted on left and right foot boards(100L,100R). The left and right foot boards are disposed on the left and right positions relative to the advancing direction of the directional casters. A connection element(300) connects the left and right foot boards. Each end portion(300L,300R) is coupled to the foot boards to pivot on the left and right foot boards and to be bent. The directional casters are mounted on the front/rear sides or the inner/outer sides of the bottom of the board or on the outer frame of the board.
