A sports board comprises a foam core, a top layer bonded to a top surface of the foam core and a bottom layer bonded to a bottom surface of the foam core. The top layer comprises a top foam layer and a top film. The top foam layer is provided for bonding to the top surface of the foam core and has patterns imprinted thereon. Additionally, the top film is bonded to the top foam layer so as to cover the patterns, which are visible through the top film. Furthermore, the bottom layer comprises a bottom foam layer and a bottom plate. The bottom foam layer is provided for bonding to the bottom surface of the foam core, and the bottom plate is bonded to the bottom foam layer.
