Abstract: A common mode filter is manufactured to include a coil part including an insulation layer and a conductor pattern formed in the insulation layer; and a magnetic substrate coupled to one surface or both surfaces of the coil part. The magnetic substrate includes: an electrostatic absorbing layer made of an electrostatic absorbing material; a magnetic layer provided on one surface or both surfaces of the electrostatic absorbing layer and made of a magnetic material; and an electrode provided between the magnetic layer and the electrostatic absorbing layer and made of a conductive material. Therefore, common mode filter may maintain high efficiency characteristics while preventing an electrostatic discharge phenomenon.

Abstract: There are provided a multilayer electronic component and a method of manufacturing the same. More particularly, there are provided a multilayer electronic component capable of maintaining high inductance at a high frequency due to excellent magnetic properties and having excellent DC bias properties and a dense fine structure to thereby improve strength, and a method of manufacturing the same.

Abstract: An electrode for a fuel cell, and a membrane-electrode assembly and a fuel cell system that include the electrode are disclosed. An electrode for a fuel cell that includes an electrode substrate, a first channel formed in the electrode substrate, a first hydrophilic interface formed on an inner surface on one side of the first channel which guides liquids, and a first hydrophobic interface formed facing the first hydrophilic interface which guides gases, makes it possible for water obtained as a side product at the cathode to be separated from air without additional devices, so that it has a potential for utilization not only in portable electronic devices but also in low-capacity power source devices.
