1. An inductor comprising:
a body including
a magnetic body containing magnetic powder, the magnetic body including principal surfaces being opposite to each other and multiple side surfaces adjacent to the principal surfaces, and
a coil embedded in the magnetic body, the coil including a winding portion in which a conductive wire is wound around and a pair of lead portions taken out from the winding portion; and
a pair of outer electrodes provided on the body, wherein
at least part of each of the lead portions is exposed from at least one side surface of the magnetic body, and is connected to a corresponding one of the outer electrodes, and
on the at least one side surface of the magnetic body on which each of the lead portions is exposed, a magnetic powder content in a region of the magnetic body closer to one of the principal surfaces with respect to a position at which each of the lead portion is exposed is higher than a magnetic powder content in a region of the magnetic body other than the region closer to the one of the principal surfaces.
