Abstract
A coil component includes a first outer magnetic body, a first outer insulator, a first inner magnetic body, an inner insulator, a second inner magnetic body, a second outer insulator, and a second outer magnetic body stacked sequentially, and a coil in the inner insulator and an internal magnetic body inside the coil. Volumes A, B, C, and D of the first and second outer insulators, the inner insulator, the coil, and the internal magnetic body, respectively, and volume E of the first outer magnetic body, the first inner magnetic body, the second inner magnetic body, and the second outer magnetic body satisfy 0.05≤A≤0.07, 0.2≤B≤0.4, 0.01≤C≤0.08, 0.03≤D≤0.05, and ≤0.4≤E≤0.71, where 0.05B≤C≤0.2B and A+B+C+D+E=1.
