Abstract
A small-sized multilayer inductor having a greatly increased inductance value includes two thin-film coils with an insulation layer interposed therebetween, the coils being disposed on a coil-winding portion of a wound-core member. At positions opposing flanges of the wound-core member, two terminal electrodes for a first thin-film coil are respectively provided. To one of the two terminal electrodes, the starting end of the first thin-film coil is electrically connected via one connection opening while the finishing end of the first thin-film coil is electrically connected to the other terminal electrode via the other connection opening. Similarly, at positions opposing the flanges of the wound-core member, two terminal electrodes, which are electrically connected to a second thin-film coil, are respectively provided.
