<p>For use as a filter, a cuboidal dielectric ceramic body includes a plurality of axially substantially parallel holes (22,23,24,25) extending between opposed side surfaces (1a,1b) of the body; a first conductive layer (3) on one of the opposed side surfaces; a second conductive layer (3) on an interior wall of each hole; and an array of substantially parallel slits (41,42,43,44,45) in one of the opposed side surfaces, a slit being located between a pair of adjacent holes, wherein a slit (41,45) towards the edge of the array is deeper than a slit (42,44) towards the centre of the array.</p> |
