A noise generation prevention device characterized in that an electric wire of an input circuit and an electric wire of an output circuit are wound into one magnetic core. The brief description of the drawing has been amended as follows. In the specification, "8" on page 6, line 13 is replaced with "8A"
and correct it. In the specification, "9" on page 6, line 14 is replaced with "9A"
and correct it.
