One aspect relates to an apparatus includes a ceramic body including a first surface and a further surface. The first surface is opposite the further surface, the first surface includes a first opening. The further surface includes a further opening. The first opening and the further opening are connected by a tunnel, which at least partly includes a tunnel filling and is occluded by the tunnel filling. The tunnel filling includes a first constituent, including a cermet, and a second constituent. The first and second constituents are electroconductingly connected to one another. The first constituent has a first electrical conductivity and the second constituent has a second electrical conductivity, which differs from the first by at least 5&#xb7;10Siemens per meter (S/m). The ceramic body is characterized by a further electrical conductivity. The first electrical conductivity is more by at least 1&#xb7;10Siemens per meter (S/m) than the 15 further electrical conductivity.

Electrical cermet feedthrough with one-piece feedthrough element having plural regions

One aspect generally relates to a composite, having a layer sequence. The layer sequence includes as layers a first layer, including a first ceramic, and first layer surface, a second layer, including a second ceramic, superimposing the first layer surface. The layer sequence includes a hole, connecting through each layer of the layer sequence; and a cermet. The cermet includes a first part and a second part. The first part is included by the hole. The second part is included between the first layer and the second layer. The cermet is in one piece.
