The invention relates to a component (11) with an antimicrobial surface (12). According to the invention, the surface (12) comprises metal portions (14) and fractions composed of MnO2 (13) that touch the former, wherein the metal fractions consist of Ag and/or Ni. It has been surprisingly shown that these material pairs achieve a much improved antimicrobial effect in comparison to the pure metals. In particular when using the toxicologically safe Ni, these antimicrobial surfaces can even be used in the food industry, for example. The surface can, for example, be applied by way of a coating (15) of the component, wherein the metal fraction and the fraction of MnO2 are applied in two layers (19, 20).
