PROBLEM TO BE SOLVED: To provide the winding structure of a stationary induction apparatus in which a serial electrostatic capacity is large and the distribution thereof can be easily adjusted. SOLUTION: This winding structure is formed by laminating and connecting a plurality of winding units (sub blocks A3, B3, C3) comprising a first differential voltage formation winding (60 to 63) formed by laminating and connecting a plurality of interleave disc windings, a parallel disc winding (64 and 65) formed by laminating and connecting a plurality of twin disc windings, and a second differential voltage formation winding (66 to 69). A serial winding circuit comprising one winding (conductor a) of the parallel disc winding forming the winding unit and the first differential voltage formation winding (60 to 63) is serially connected with a serial winding circuit comprising the other winding thereof (conductor b) and the second differential voltage formation winding (66 to 69), and the number of windings of the differential voltage formation winding forming the winding unit is set to be large in a unit connected with the end of a power supply.
