To provide a generator which not only reduces magnetic force resistance but also improves power generation efficiency.SOLUTION: A generator comprises: a cylindrical rotor 3 which is fitted to a rotary shaft 2 that is supported in a housing in a rotatable manner; a cylindrical inner stator 4 which is disposed concentrically with the rotor 1 that is fixed in the housing 1; and a cylindrical outer stator 5 which is concentrically disposed outsides. In a rotation direction of the rotor 3, multiple permanent magnets 31 are disposed cylindrically in such a state that magnetic poles become alternately different. Multiple coils 41 and 51 which generate AC voltages when the rotor 3 is rotated, are juxtaposed at positions facing the permanent magnets 31 disposed in the rotor at sides of the inner stator 4 and the outer stator 5 facing the rotor. At least one of the coils 41 and 51 disposed in the inner stator 4 and the outer stator 5 is defined as a high inductance coil.SELECTED DRAWING: Figure 1 【課題】磁力抵抗を少なくするだけでなく発電効率に優れた発電機を提供する。【解決手段】ハウジング１に回転可能に支持された回転軸２に取り付けられた円筒状の回転子３と、ハウジング１に固定された回転子１と同心に配置された円筒状の内側固定子４および外側に同心に配置された円筒状の外側固定子５有し、回転子３回転方向に複数の永久磁石３１を磁極が交互に異なる状態に円筒状に配置されているとともに内側固定子４および外側固定子５は回転子に対峙する側に回転子に配置された永久磁石３１に対向する位置にそれぞれが回転子３を回転させたときに交流電圧を発生させる複数のコイル４１，５１が並設されており、内側固定子４および外側固定子５に配置されているコイル４１，５１の少なくとも一方を高インダクタンスコイルとした。【選択図】図１
