摘要： Provided is a reactor including a coil, and a core having an inner core portion arranged inside the coil and an outer core portion covering the outside of the coil. The inner core portion of the reactor has a higher saturation magnetic flux density than that of the outer core portion. The outer core portion has a lower permeability than that of the inner core portion, and is made of a mixture of a magnetic material and a resin. The case has a heat-transfer portion at an inner wall surface, as a heat-radiation structure for at least one of the coil and the inner core portion. With the reactor, even if the outside of the coil is covered with a core member, heat generated in the reactor can be effectively dissipated.

A small reactor capable of reducing magnetic flux leaked to the outside is thereby provided. A method of producing a small reactor capable of reducing magnetic flux leaked to the outside is also provided which produces the reactor 1α by filling the case 4 with a mixture of magnetic powder, non-magnetic powder, and resin, producing a state where the non-magnetic powder has floated to the opening side of the case 4 and the magnetic powder has precipitated on the bottom side of the case 4, and hardening the resin.

摘要： A reactor 1 of the present invention includes a coil 2 and a magnetic core 3 disposed inside and outside the coil 2 to form a closed magnetic path. At least part of the magnetic core 3 is made of a composite material containing a magnetic substance powder made of an identical material and a resin containing the powder being dispersed therein. In the particle size distribution of the magnetic substance powder, a plurality of peaks are present. That is, the magnetic substance powder contains both a fine powder and a coarse powder at high frequencies. Since the composite material contains the fine powder, it can reduce the eddy current loss, and hence achieves to be a low-loss material. Thanks to the mixed powder including the fine powder and the coarse powder, the packing density of the magnetic substance powder is increased. Thus, the composite material exhibits a high saturation magnetic flux density. By employing such a mixed powder, the raw material powder can be handled with ease, and excellent manufacturability of the composite material is obtained.
