COIL COMPONENT

In the coil component, the maximum reference surface height of the entire wall of the outermost wall and the innermost wall is the same as the reference surface height of the winding part of the coil, that is, equal to or less than the reference surface height of the winding part of the coil.

description In the coil component, the maximum reference surface height of the entire wall of the outermost wall and the innermost wall is the same as the reference surface height of the winding part of the coil, that is, equal to or less than the reference surface height of the winding part of the coil. In addition, in both the outermost wall and the innermost wall, the reference surface height of the second side surface is lower than the reference surface height of the winding part of the coil. In this case, in the vicinity of the upper surface of the outermost wall and the innermost wall, the magnetic flux toward the main surface side of the substrate is suppressed from being blocked by the outermost wall and the innermost wall, and the magnetic flux circulation is improved. Thus, the coil characteristics of the coil component are improved.
