ABSTRACT:
A noise filter including semi-conductor ceramics having voltage non-linearity characteristics. End surface electrodes are formed on a pair of opposing end surfaces of the semi-conductor ceramics and side surface electrodes are formed on a pair of side surfaces thereof. A first inner electrode is formed inside the semi-conductor ceramics having one end surface electrically connected to one of the end surface electrodes. A second inner electrode is formed inside the semi-conductor ceramics so as to be overlapped with the first inner electrode and separated therefrom by a ceramic layer. Both end surfaces of the second inner electrode are electrically connected to the pair of side surface electrodes. At least one resistance layer is embedded in the semi-conductor ceramics so that both end surfaces of the resistance layer are electrically connected to the pair of end surface electrodes.
