The present invention relates to an aircraft wing. The aircraft wing includes: a lightning protection device installed on the surface of the aircraft wing to deliver electric energy of lightning to surroundings when a lightning strike occurs, and having a pattern engraved on a metal plate; and an electromagnetic wave absorption device installed in contact with the lightning protection device to absorb electromagnetic waves, and including an electromagnetic wave absorption layer formed of dielectric fibers. The pattern of the lightning protection device includes a first parallel part including a plurality of parallel lines, a second parallel part including a plurality of parallel lines, forming a plurality of square cells orthogonally to the first parallel part, and a circular cross reinforcement part including a part in which the first and second parallel parts cross with each other. Therefore, the present invention is capable of effectively absorbing electromagnetic waves.
