Zusammenfassung:	To provide an electric aircraft which has a simple and lightweight structure, and improves lightning resistance reliability.SOLUTION: An electric aircraft includes a machine body, a plurality of structure skeleton members provided on the machine body, fan motors provided on each of the structure skeleton members, and tip electric field concentration parts provided on the ends of the structure skeleton members, wherein the impedances of the structure skeleton members are lower than the impedance of the fan motor, and accordingly when lightning strikes the electric aircraft, current flows in not the fan motor but the structure skeleton members. Thereby, damage to the fan motor by lightning strike can be avoided.SELECTED DRAWING: Figure 1 【課題】さらに簡素で軽量な構成を有し、耐雷信頼性が向上した電動航空機を提供する。【解決手段】電動航空機は、機体と、機体に設けられた複数の構造骨格部材と、構造骨格部材にそれぞれ設けられたファンモータと、構造骨格部材の端部に設けられた先端電界集中部と、を備え、構造骨格部材のインピーダンスは、ファンモータのインピーダンスよりも低い。構造骨格部材のインピーダンスがファンモータのインピーダンスよりも低いため、電動航空機に落雷が生じた時に、電流はファンモータではなく、構造骨格部材を流れる。これにより、雷撃によるファンモータの損壊を回避することができる。【選択図】図１
