A composite material wing structure is disclosed, comprising a plurality of composite material multi-spar structures, each including a plurality of spar extending in a span direction, placed in the span direction. A wing structure of an airplane is also disclosed, comprising wing structures divided into plural parts in a span direction, a rib connected to an end of the wing structure to assemble adjacent wing structures, and a coupling material for coupling spars of the adjacent wing structures.

[ What is claimed is:] [1.]1. A wing structure comprising:a leading edge portion provided in a front portion of said wing structure for extending in a spanwise direction thereof and for initially separating a circumifluent fluid to an upper surface and a lower surface thereof when said circumfluent fluid flows on both surfaces in a chord direction,an inter-spar structure connected to a rear end of said leading edge portion for extending in said spanwise direction, anda trailing edge portion connected behind said main inter-spar structure portion for forming a rear edge portion of said wing structure in said spanwise direction,said inter-spar structure is divided into a plurality of multi-spar structure portions in said spanwise direction, and each is made from a composite material;an upper skin is provided on each of said inter-spar structure portion for forming a smooth and continuous inter-spar surface from said upper surface of said leading edge portion to an upper side of said trailing edge portion;a lower skin is provided under said multi-spar structure portion for forming an lower continuous surface from said lower surface of said leading edge portion to a lower side of said trailing edge portion;a front spar is provided between said leading edge portion and said multi-spar structure portion and between said upper and lower skins for connecting said leading edge portion; anda rear spar is provided between said multi-spar structure portion and said trailing edge portion and between said upper and lower skins for connecting said trailing edge portion with said multi-spar structure portion so as to easily and accurately manufacture said wing structure with a long span by dividing said multi-spar structure portion into a plurality of units.
