Abstract
When an inductor component is adopted as an inductor for a DC-DC converter, high efficiency is achieved at a light load, and a large current is also handled. An inductor component includes a body containing metal magnetic powder containing an iron element, and an inductor provided in the body and having both ends exposed from the body. In a DC superposition characteristic curve of the inductor, a first steady region and a second steady region exist as a steady region, and a transition region exists between the first steady region and the second steady region.
