In the case of a metal-ceramic substrate with a multilayered ceramic material in sheet form, and with at least one metallization that is provided on one surface side of the ceramic material and is joined to be ceramic material by direct bonding or active soldering, the ceramic material has at least one inner layer or base layer of a silicon nitride ceramic. The surface side of the ceramic material that is provided with the at least one metallization is formed by an intermediate layer of an oxidic ceramic applied to the base layer.
