Abstract
In an insulation layer of a coil component, a thickness of a second covering part and a third covering part located on the penetration hole side of a first covering part is thinner than that of the first covering part. A stray capacitance occurring between a flat coil pattern and external terminal electrodes is reduced by making the first covering part of the insulation layer thicker than the second covering part and the third covering part. Further, since the second covering part and the third covering part of the insulation layers are thinner than the first covering part, a magnetic volume is increased while external dimensions of the base body is maintained, and thus a high inductance is realized.
