Abstract
The electromagnetic interference suppressing device of the present invention includes a plurality of connection layers and ground layers formed of a conductive material. The connection layers and the ground layers are alternately layered. Insulating layers, formed of an insulating material, intervene between the neighboring connection layers and ground layers. The odd connection layers counting from the bottom and the connection layers just above those layers are electrically connected at the same end. The even connection layers counting from the bottom and the connection layers just above those layers are electrically connected at the same end opposite to the odd connection-layered end. The bottommost connection layer is connected to a first signal terminal. The uppermost connection layer is connected to a second signal terminal. The ground layer is connected to a ground terminal.
