<P>PROBLEM TO BE SOLVED: To form a dihedral angle as well as a steric wing having high-capacity lift at the same time, and improve the strength of the wing while easily fabricating a paper airplane by joining parts cut out of a sheet material with an adhesive glue. Ž<P>SOLUTION: The square-like sheet material S is cut so as to be shaped like the main wing 2 of the paper airplane 1. A rear-end edge 2a on the upper side of two overlapped portions of the main wing 2 is shifted toward the side of a main wing crease-line WF and is pasted with an adhesive B so as to form a hollow portion in the main wing 2. A portion of center crease line CF of the main wing 2 and both portions of the sheet material S folded to the side of the center crease line CF are pasted together on the bottom surface of the body 5 with the adhesive B so as to form the dihedral angle by which both wing-tips of the main wing 2 can be lifted. The paper airplane is fabricated by the method. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
