SKI BOARD

PROBLEM TO BE SOLVED: To provide a ski board, securing stable and high rectilinear propagation performance and improved in operability in turning. SOLUTION: This ski board 5 includes: a plate-like member 59 where a pair of rectilinear side wall parts 61, 63 are formed along the longitudinal direction; a forward bulged member 65 where forward bulged parts 69, 71 gradually increased in width of outward projection along the longitudinal direction as it goes toward the front end part 5a are formed symmetrically at the upper end sides in the paired rectilinear side wall parts 61, 63, and a backward bulged member 67 where backside bulged parts 73, 75 gradually increased in width of outward projection along the longitudinal direction as it goes toward the rear end part 5b are formed symmetrically at the upper end sides in the paired rectilinear side wall parts 61, 63. Stepped parts 77, 79 are respectively formed by the paired rectilinear side wall parts 61, 63 and the forward bulged parts 69, 71, and the paired rectilinear side wall parts 61, 63 and the backside bulged parts 73, 75.
