Abstract
A multilayer common mode filter includes: a body including a coil part having a plurality of spiral coils, wherein the coil part has one lead portion connected to one of external electrodes disposed on the body and one or more dummy lead portions each connected to the other external electrodes, and the lead portion is connected to dummy lead portions of other coil layers stacked in a thickness direction in series. Therefore, even though the common mode filter is miniaturized, the common mode filter may secure predetermined levels or more of performance and reliability.
