| description | The purpose of the present invention is to obtain a high inductance value while reducing the overall thickness of a coil component having a structure in which a spiral coil pattern is laminated. A coil component (1) is provided with: a coil section (C) having a structure in which interlayer insulating films (51-55) and coil patterns (CP1-CP4) wound in a spiral shape are alternately laminated in the axial direction; and magnetic element bodies (M1-M3) embedded in the coil part (C). An interlayer insulating film (55) covering the coil pattern (CP4) located at one end in the axial direction from the one end in the axial direction has higher magnetic permeability than other interlayer insulating films (51-54). Thus, the coil pattern (CP4) located at the end portion is covered by the interlayer insulating film (55) having a high magnetic permeability, so that a high inductance value can be obtained in a state where the overall thickness is thin.
本发明的线圈部件的目的在于，在具有层叠有螺旋状的线圈图案的构造的线圈部件中，使整体的厚度薄，并且得到高的电感值。线圈部件(1)包括：线圈部 |
