PROBLEM TO BE SOLVED: To provide a stationary induction apparatus that can be manufactured economically by effectively arranging a non-magnetic material shield on the inner wall face of a tank and reduces loss, while suppressing temperature rise, based on leakage magnetic flux. SOLUTION: A transformer body 11 is configured such that each winding W is respectively wound around an iron core main leg 21 of each phase; the transformer body is stored inside a tank 10; and the tank 10 is composed such that a non-magnetic material shield 30, formed larger than an axial dimension of each winding, is mounted at least onto the inner wall face in the tank longitudinal direction facing each winding. Each of the non-magnetic material shield 30 has a belt-like blank part 31, respectively formed near the part facing the axial upper-end side or the axial lower-end side of each winding. Each of the non-magnetic material shield 30 is constituted of a horizontal shielding member 31A, which is divided into three parts in the horizontal direction of the tank 10 by the belt-like blank part 31, and each connecting shielding member 30B that is arranged on the inner wall face, which does not facing each winding, of the tank 10 so as to connect the horizontal shielding members 31A.
