The snowboard comprises an injected core (5) which is surrounded by a separator film (4) in contact with internal fibrous reinforcement on the internal wall. The procedure for manufacture consists in providing in the space where the injection is to be made, an injection hole (10) which passes through the board external structure (1). This hole has an injection eyelet (12) made of plastics and of the same colour as the board core. The eyelet can be of aluminium. The polyurethane core is injected by a nozzle (11) through the eyelet in order to avoid contact of the polyurethane with the reinforcing resinous material (3). After completing the injection operation the eyelet external collar (24) is removed.
