Abstract
A common mode choke coil comprising a core; a first wire and a second wire wound around the core; a first electrode part and a second electrode part disposed on the core and connected to the first wire; and a third electrode part and a fourth electrode part disposed on the core and connected to the second wire. The common mode choke coil has a self-resonance frequency of 700 MHz or more, and a common mode inductance of 300 nH or less, in a frequency band of 1 MHz or less.
