A board for sporting purpose, such as a skateboard or a surfboard, includes an upper and a lower layer, and an intermediate layer sandwiched between the upper and lower layers. The intermediate layer is formed from a plurality of elongate supporting members that extend in a longitudinal or moving direction (Y-direction) of the board and are horizontally and parallelly arranged in a transverse direction or X-direction of the board. Each supporting member has a cross section of suitable shape and dimensions, and is coated over all outer surfaces with a layer of fibrous fabric, making the whole intermediate layer a light and three-dimensionally reinforcedg layer for the board, so that the board has increased rigidity and torsional strength and reduced weight in unit thickness to provide upgraded quality for use.
