Summary:PROBLEM TO BE SOLVED: To suppress electric field concentration in end parts on the outer periphery side and inner periphery side of an electrostatic shield while suppressing the electrostatic shield from being thickened.SOLUTION: The stationary induction apparatus includes: an iron core; a winding wound around the iron core as a central axis; an annular electrostatic shield 150 arranged adjacent to at least one side of ends of the winding in a direction running along the central axis. The electrostatic shield 150 includes a conductor part 152 and a second insulation coating part 153 covering the conductor part 152. A potential of the electrostatic shield 150 is lower than a highest potential in the winding.SELECTED DRAWING: Figure 5 【課題】静電シールドが厚くなることを抑制しつつ、静電シールドの外周側および内周側の端部における電界集中を抑制する。【解決手段】鉄心と、鉄心を中心軸として巻き回された巻線と、上記中心軸に沿う方向における巻線の端部の少なくとも一方に隣接して配置された環状の静電シールド１５０とを備える。静電シールド１５０は、導体部１５２および導体部１５２を被覆する第２絶縁被覆部１５３を含む。静電シールド１５０の電位は、巻線における最も高い電位より低い電位である。【選択図】図５
