Claim Text:
1. A laminated coil component comprising: a magnetic body part made of a ferrite material; and a conductor part wound into a coil shape, the conductor part being embedded in the magnetic body part to form a component base, wherein the component base is divided into a first region near the conductor part and a second region other than the first region, the grain size ratio of the average crystal grain size of the magnetic body part in the first region to the average crystal grain size of the magnetic body part in the second region is 0.9 or less, the ferrite material contains at least a Cu component, the content of the Cu component is 0.2 to 4 mol % in terms of CuO, and the first and second regions of the component base are magnetic.
