The invention relates to an ignition coil with iron powder-containing core for motor vehicles. According to the invention, the ignition coil consists of two low-voltage terminals (1 and 1'), a primary winding (2), a secondary winding (3), a magnetic core (4) made of iron powder, coated in a thin film of organic or inorganic compound, which is then mixed with 0.5 % lubricant and 0.5 - 3 % of a thermoresistant resin-type binder, having the magnetic induction 17.0 ... 17.3 KGs, the coercive magnetic field intensity of 10 ... 15 Oe, the maximum magnetic permeability of 154-480, total magnetic losses of 0.55 W/kg at an operating temperature range from - 55 degree to + 125 degree C.
