To provide a safe stationary induction electrical apparatus that prevents a fragment coming off a magnetic shield, wound around an iron core leg portion of the stationary induction electrical apparatus, due to vibrations from being released in a tank accommodating the stationary induction electrical apparatus and thus prevents a trouble such as dielectric breakdown. Moreover, to provide a stationary induction electrical apparatus that does not need to be changed in the dimensions of an iron core for securing an insulation distance due to the placement of a magnetic shield and can reduce a compressive force generated in a winding. A magnetic material is provided in the interiors of insulating members whose interiors are hollow and which are provided in the vicinities of upper and lower ends of the winding wound around the iron core leg portion of the stationary induction electrical apparatus.
