Abstract: Disclosed herein is a coil component that includes an insulating substrate, a first coil part formed on the first surface of the insulating substrate, and a second coil part formed on the second surface of the insulating substrate. At least an innermost turn of the first coil part is radially separated by spiral-shaped slits into three or more conductor parts. At least an innermost turn of the second coil part is radially separated by spiral-shaped slits into three or more conductor parts. Inner peripheral ends of respective innermost to outermost conductor parts of the three or more conductor parts of the first coil part are connected to inner peripheral ends of the respective outermost to innermost conductor parts of the three or more conductor parts of the second coil part.
