Abstract

A component includes a substrate layer (1) of glass or Al.sub.2 O.sub.3, an anti-reaction layer (2) or a levelling layer (2), two electrode layers (3, 5) and a dielectric layer (4) as well as such a capacitor. Manufacture a component which provides for cost-effective, surface-mountable (SMD). The anti-reaction layer (2) on the glass substrate (1) or the levelling layer (2) on the Al.sub.2 O.sub.3 -substrate (1) is made of at least one specific material. An anti-reaction layer or a levelling layer (2) of one of the above-mentioned substances or a combination of several substances, enables a dielectric layer (4) to be provided by means of which a high capacitance value is achieved.
