    摘要: An inductor includes an element containing a magnetic metal powder and a resin, a coil that includes a winding portion and paired extended portions extended from both ends of the winding portion and that is embedded in the element, a pair of an external terminal electrically connected to one of the extended portions and an external terminal electrically connected to the other of the extended portions, and a conductive layer disposed on a surface of the element that crosses the winding axis of the coil. The conductive layer includes a first metal layer formed by fusing together the magnetic metal powder near the surface of the element and a second metal layer formed by plating on the first metal layer. The electrical resistivity of the second metal layer is lower than the electrical resistivity of the first metal layer.
