The coil form according to the invention for forming an inductive element includes a hollow cylindrical mantle portion, two flange portions and a slit. The flange portions and the mantle portion form a winding chamber for winding therein a wire that forms a first winding or a part of a first winding of the inductive element. The coil form, which is completely made of copper, forms a second coil or a winding of a second coil of the inductive element. Due to the increased contact surface between the first and the second coil the heat dissipation capabilities and the magnetic coupling between the coils are increased. This in turn results in an increased power density of the inductive element.
