COIL COMPONENT

To provide a coil component which enables the reduction in thickness, and which is superior in saturation current, inductance, magnetic permeability and core loss value.SOLUTION: A coil component 1000 comprises: a main body 100 having one face 105 and the other face 106 opposed to each other, and a plurality of wall faces 101, 102, and so on, in which the distance from the one face 105 to the other face 106 is 0.65 mm or less (except 0); and a coil part 300 buried in the main body 100. The main body 100 contains Fe-Si-B-Nb-Cu based metal magnetic powder represented by the chemical formula 1 below. The Fe-Si-B-Nb-Cu based metal magnetic powder includes crystal grains of 20 nm or smaller (except 0). [Chemical Formula 1] FeSiBNbCu(where 73 atom%≤a≤77 atom%, 10 atom%≤b≤14 atom%, 9 atom%≤c≤11 atom%, 2 atom%≤d≤3 atom%, 0.5 atom%≤e≤1 atom%, and a+b+c+d+e=100).SELECTED DRAWING: Figure 2
