COIL COMPONENT

摘要

To provide a coil component that achieves both low stray capacitance and high inductance. A coil component 1 includes a first coil block 2 and a second coil block 3 that are sandwiched between magnetic substrates 4-1, 4-2 so as to form a chip body, and external electrodes 5-1 to 5-4 that are attached to the chip body. The first coil block 2 (3) includes a coil body 2-1 (3-1) and an insulating body 2-2 (3-2). The coil body 2-1 (3-1) includes an outer coil portion 6 (6') and an inner coil portion 7 (7'). The outer coil portion 6 (6') includes a first pattern group 6-1 and a second pattern group 6-2, which are connected helically vertically in an alternating fashion. The inner coil portion 7 (7') includes a first spiral pattern 7-1 and a second spiral pattern 7-2, which are connected to each other in series. In other words, low stray capacitance is achieved by means of the outer coil portion 6 (6'), while high inductance is achieved by means of the inner coil portion 7 (7').
