PROBLEM TO BE SOLVED: To obtain a sheet wound stationary induction electric apparatus, which is rugged against an electromagnetic mechanical stress and has leads which are easily connected. SOLUTION: Connection parts 26 are respectively provided on the winding start and winding end parts of a metal sheet 13 on a cylindrical wound wire main body part 12. The connection parts 26 are ones formed by soldering a tabular leads 28 with a section formed into a circular arc shape on connection sheet parts 27, which are the end parts of the sheet 13. As the leads 28 formed into the circular arc shape are provided in such a way as to extend along the outer and inner peripheral parts of the main body part 12, an irrational stress is not applied to the connection parts 26 and the connection parts 26 can stand a strong electromagnetic stress. Moreover, as the leads 28 are a circular arc-shaped plate, the connection of the leads 28 with the sheet parts 27 is also easy.
