    Abstract: A coil device includes first and second wires, a drum core having a winding part around which the wires are wound. The drum core has first and second flanges formed at different ends of the winding core part along the first axis. First and second terminals which connect with the first wire are formed at the first flange, and third and fourth terminals which connect with the second wire are formed at the second flange. The first wire has a first coil part having a winding width W1 wound around the winding core part, and the second wire has a second coil part having a winding width W2 wound around the winding core part. The first coil part is arranged closer to the first flange and it is spaced apart from the second coil part by taking a distance W3, and W3>W1 or W3>W2 is satisfied.

    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: 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: Disclosed herein is a coil component that includes a winding core part and a wire wound around the winding core part. An i-th turn (i is an integer equal to or larger than 1) to a j-th turn (j is an integer equal to or larger than (i+2)) of the wire are wound in this order around the winding core part in an aligned state. A (j-th+1) turn of the wire is wound around a valley line formed by the i-th turn and a (i-th+1) turn. A (j-th+2) turn of the wire is wound adjacent to the j-th turn around the winding core part.

    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.
