Abstract:
1. A noise filter comprising: a dielectric element formed of a stack of dielectric layers; a pair of first terminal electrodes disposed on one face of the dielectric element and each connectable to an external circuit; a second terminal electrode disposed on the face on which the pair of first terminal electrodes exist and connectable to the external circuit; a pair of first internal conductors having bent portions respectively and disposed in the dielectric element with both ends thereof being led out outside the dielectric element and with the respective ends thereof on one side being led out to different portions from each other and individually connected to the pair of first terminal electrodes; a coupling electrode disposed on a face of the dielectric element opposite to the face on which the pair of first terminal electrodes are disposed, and connecting the other ends of the pair of first internal conductors each other; and a second internal conductor which is arranged at least between the pair of first internal conductors in the dielectric element, being separated from the pair of first internal conductors by the dielectric layers, and whose one end is led out to the face of the dielectric element to be connected to the second terminal electrode.
