ABSTRACT:
A coil component includes a first coil block and a second coil block that are sandwiched between magnetic substrates so as to form a chip body, and external electrodes that are attached to the chip body. The first coil block includes a coil body and an insulating body. The coil body includes an outer coil portion and an inner coil portion. The outer coil portion includes a first pattern group and a second pattern group, which are connected helically vertically in an alternating fashion. The inner coil portion includes a first spiral pattern and a second spiral pattern, which are connected to each other in series. In other words, low stray capacitance is achieved by the outer coil portion, while high inductance is achieved by the inner coil portion.
