Abstract: Disclosed herein is a common mode filter that includes a core having a winding core part and first and second wires wound in a same direction around the winding core part. The first and second wires have a first crossing portion at which first turns thereof counted from one ends thereof cross each other and a second crossing portion at which first turns thereof counted from the other ends thereof cross each other. The first and second wires are wound by layer winding in an aligned state with one of the first and second wires positioned in a lower layer and other one thereof positioned in an upper layer in at least parts of the first and second wires between second turns thereof counted from the one ends thereof and second turns thereof counted from the other ends thereof.

Abstract: Disclosed herein is a coil component that includes a winding core part and a wire wound around the winding core part. The winding core part includes a first winding area positioned on a first flange part side, a second winding area positioned on a second flange part side, and a third winding area positioned between the first and second winding areas. The wire includes a first section wound in a plurality of turns around the first winding area, a second section wound in a plurality of turns around the second winding area, and a third section wound in less than one turn around the third winding area. A shift amount of a winding position of the wire in an axial direction per turn is larger in the third section than in each of the first and second sections.

Abstract: An ESD suppressor is configured including first and second discharge electrodes arranged as separated from each other, and a discharge inducing portion kept in contact with the first and second discharge electrodes so as to connect mutually opposed portions of the first and second discharge electrodes to each other. The discharge inducing portion contains metal particles. The first and second discharge electrodes are located on the coil side with respect to the discharge inducing portion when viewed in a stack direction of a plurality of insulator layers. An element body has a cavity portion located so as to cover the whole of the discharge inducing portion when viewed in the stack direction from the coil side. The cavity portion is in contact with the mutually opposed portions of the first and second discharge electrodes and with the discharge inducing portion.

Abstract: The composite electronic component includes: a substrate having a GND pattern; a coil component having at least three terminals and mounted on a first surface of the substrate; and an overlapping arrangement component mounted on the first surface so that at least a part of the overlapping arrangement component overlaps the coil component when viewed from a first direction perpendicular to the first surface. The substrate has at least three coil connection patterns formed on the first surface and connected to the terminals, at least two component connection patterns formed on the first surface and connected to the overlapping arrangement component, and a GND via connecting one of the component connection patterns and the GND pattern to each other. The GND via is arranged in a substrate outer region, which is outside a region of a hypothetical polygon connecting all of the coil connection patterns on the substrate with a shortest perimeter, when viewed from the first direction.
