To provide a stator capable of reducing an eddy current loss generated in a flat angle coil.SOLUTION: A stator 1A comprises: a stator iron core 10A having a plurality of slots 12 which opens in an inner peripheral surface 11 and a plurality of teeth 13A formed between adjacent slots 12; and a flat angle coil 20A wound to each of the teeth 13A. In the stator, since each of the teeth 13A contains a wide width part 15 that a width W of a peripheral direction Dc of the inner peripheral surface 11 is increased as close to the inner peripheral surface 11 in a cross-sectional view by a cross section orthogonal to a rotational axis 51 of a rotator 50 surrounded by the stator iron core 10A, a flux saturation is hardly generated, a leakage flux is reduced, and an eddy current loss generated in the flat angle coil 20A can be reduced.SELECTED DRAWING: Figure 2 【課題】平角コイルで発生する渦電流損を低減することができる固定子を提供する。【解決手段】内周面１１に開口する複数のスロット１２と、互いに隣接するスロット１２の間に形成された複数のティース１３Ａとを有する固定子鉄心１０Ａと、ティース１３Ａのそれぞれに巻回された平角コイル２０Ａとを備えた固定子１Ａにおいて、固定子鉄心１０Ａが囲繞する回転子５０の回転軸５１に直交する断面による断面視で、ティース１３Ａは内周面１１に近づくほど内周面１１の周方向Ｄｃの幅Ｗが増大する拡幅部１５を含むため、磁束飽和を発生し難くし、漏れ磁束を低減し、平角コイル２０Ａで発生する渦電流損を低減することができる。【選択図】図２
