Claim:
1. A laminated coil component comprising: a magnetic body part made of a ferrite material, a conductor part including a portion wound into a coil shape embedded in the magnetic body part, wherein a first region of the magnetic body part and a second region of the magnetic body part are disposed along a line perpendicular to a central axis of the coil-shape, the first region being disposed near the conductor part, the second region being spaced from the coil-shaped portion, the central axis of the coil-shape extends in a stacking direction of the laminated coil component, 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 0.85 or less and greater than 0, and the conductor part contains Cu as a main component.
