A wideband noise reducing device has a three level structure including a magnetic member comprising at least one magnetic film, and first and second boards disposed on both sides of the magnetic member so that the magnetic member is sandwiched between the first and second boards. Each of the first and second boards has a signal pattern portion. The signal pattern portions of the first and second boards are connected with each other to form a signal line wound around the magnetic member.
