Abstract:
A chip-type coil component capable of reducing the resistance of the coil while minimizing a decrease in the inductance of the coil includes magnetic layers composed of a multilayer body. The chip-type coil component further includes internal electrodes laminated on the magnetic layers. The internal electrodes are connected to each other to form a coil. The chip-type coil component further includes an auxiliary internal electrode laminated on each of the magnetic layers. Each auxiliary internal electrode is connected in parallel to the internal electrode laminated on the magnetic layer that is different from the magnetic layer on which the auxiliary internal electrode is laminated.
