PROBLEM TO BE SOLVED: To provide wings of a surface effect craft capable of sustaining the pressure of water and air and of being embodied at low cost in a lightweight construction and to provide a manufacturing method for wings. SOLUTION: The surface effect craft having tandem type wings is structured so that the front wings 2 and rear wings 3 protruding aside from the side planks of the hull 1 exert a surface effect, in which the wings are embodied in a load multipath transmitting structure, characterized by that the front portions 12, side plates 9, and bottom outer plates 8 of the front 2 and rear wings 3 are formed in a single piece from FRP, and that the wings 2 and 3 are furnished internally with a plurality of longitudinal beams 4 and transverse beams 5, in order to establish the load multipath transmitting structure where the longitudinal beams 4 and transverse beams 5 cross each other to form a grating.
