Abstract
An electrical cable for high-voltage circuits is used in fixed type apparatuses such as office or home appliances. The electrical cable includes a tubular core portion formed of fluorine rubber and a magnetic material mixed therewith. The tubular core portion is wound with a conductive wire. The diameter of the conductive wire is set to be about 40 &mgr;m at the most, so that number of spirals can be more than about 10,000 spirals/m. Under these conditions, even when the electrical cable is flexed, spirals of the conductive wire are prevented from being superposed or stacked. The electrical cable can thus be provided with a high impedance and prevented from noise penetration.
