摘要： A common-mode choke coil has induction immunity characteristics that are improved by a coil structure preventing a transmitter IC and a receiver IC from malfunctioning during an induction immunity test and which controls a decrease in ESD resistance and a decrease in self-resonance frequency. The common-mode choke coil includes a core, external electrodes, a pair of coils, and a top plate. The core includes a core section and a pair of flange sections. The pair of coils are wound around the core section of the core, and the ends of the coils are connected to the external electrodes, respectively. An underside and a side surface of the top plate are plated with a metal film, and bonded to the top surfaces of the flange sections preferably by an adhesive agent. The metal film is segmented into two separate portions so as to define two separate metal sections with a gap therebetween so that the metal sections are electrically disconnected.
