Abstract: A laminated coil component includes a magnetic body part made of a Ni—Zn-based ferrite material and a coil conductor containing Cu as a main component, which is wound into a coil shape, and the coil conductor is embedded in the magnetic body part to form a component base. The component base is divided into a first region near the coil conductor and a second region other than the first region.
