To provide an unmanned flying body that has improved calmness.SOLUTION: An unmanned flying body 1 flies by obtaining thrust from the rotation of propellers 12A-12F respectively connected to multiple motors 10A-10F, where those propellers are arranged so that center locations of rotation surfaces of adjacent propellers have a predetermined difference in height. The predetermined difference in height is defined within a range where a decrement of sound which is generated by the rotation of propellers is relatively large.SELECTED DRAWING: Figure 1

    【課題】静謐性を向上した無人飛行体を提供する。【解決手段】無人飛行体1は、複数のモーター10A〜10Fにそれぞれ接続されるプロペラ12A〜12Fの回転によって推力を得て飛行し、隣り合うプロペラの回転面の中心位置が、所定の高低差を有するようにプロペラを配置する。前記所定の高低差は、プロペラの回転によって生じる音の減少率が相対的に大きい範囲において規定する。【選択図】図1
