A ceramic pressure sensor is described which is produced using an alternative production method and has a ceramic base body, a ceramic measuring membrane which is disposed on the base body and is to be charged with a pressure to be measured, and a pressure measuring chamber enclosed in the base body below the measuring membrane. A method to produce the pressure sensor by means of which, in particular, more complex shapes of the measuring membrane and/or the base body are producible with minimal pores wherein the base body and/or the measuring membrane have layers applied on each other in a 3-D printing method and produced by the selective laser melting of nanopowder layers.
