Abstract: Disclosed is a sensor having an embedded electrode, which can be manufactured at a reduced cost and applied to many different fields. The sensor comprises: a sensing stack in which a first conductive layer and a second conductive layer are stacked and layered with a separation layer interposed therebetween; and an electrode terminal arranged at a side surface of the sensing stack and electrically connected to the first and second conductive layers. The first and second conductive layers are exposed on at least one side surface of the sensing stack except for the side surface on which the electrode terminal is arranged, to thereby form a sensing surface.

Abstract: A lead-through type filter used in a dc line for removing noises is disclosed. The lead-through type filter having angular elements according to the present invention includes a case 25 to be used as an external grounding terminal. A central conductive line 21 supplies a dc power and serves as IN/OUT terminals. At least one angular filtering element made of an angular ceramic stock is accommodated within the case. One side electrode is attached on a face of the ceramic stock and is electrically connected to the case 25. Another side electrode is attached on another face of the ceramic stock and is electrically connected to the central conductive line 21. An epoxy resin is filled into the interior of the case 25. Instead of the conventional lead-through type capacitor, polygonal capacitors are used in the present invention, and therefore, the capacitance control becomes easy, while the errors can be minimized.
