Coil component

A coil component, comprising:

• a magnetic body of rectangular solid shape;
• a coil with N turns (N is a positive number of 2 or greater) provided inside the magnetic body, which has:
• a first conductor layer having a first multiple winding part which is wound around one axis with a first spacing;
• a second conductor layer having a second multiple winding part which is wound around the one axis with the first spacing and faces the first conductor layer;
• and
• an inter-layer connection part that inter-connects an inner periphery end of the first multiple winding part and an inner periphery end of the second multiple winding part;
• an insulating intermediate part which is provided inside the magnetic body and forms, between the first conductor layer and second conductor layer, a second spacing corresponding to a thickness equal to or less than a product of the first spacing and (N−1), said insulating intermediate part having an electrical resistance higher than that of the magnetic body;
• and
• external electrodes provided on the magnetic body and connected, respectively, to outer periphery ends of the first and second multiple winding parts.
