A method for production of a pressure sensor comprising a flat flexible membrane made of a ceramic material and a flat rigid support thereof made of a ceramic material, comprising the following steps: - providing a first sheet-like workpiece having a first main face and a second main face, the first workpiece defining a plurality of membranes; - providing a second sheet-like workpiece having a first main face and a second main face, the second workpiece defining a plurality of supports; - realising an electric circuit (16, 18) on the membranes on the first main face of the first sheet-like workpiece, the electric circuit comprising conductive tracks; - realising an electric contact with the outside on the supports; - depositing an electrically conductive material on the supports on the first main face of the second sheet-like workpiece in order to form conductive tracks; characterised in that: - a layer of electrically conductive sinterable electrical connection material is printed on said supports on the second main face of said second workpiece, on top of the conductive tracks, and then sintered in a sintering furnace; - a layer of electrically conductive sinterable electrical connection material is printed on top of the conductive tracks; - a respective layer (13, 21) of sinterable mechanical connection material is printed on said membranes on the first main face of said first workpiece and on said supports on the second main face of said second workpiece, respectively, and then sintered in the furnace, the layer of sinterable mechanical connection material being electrically insulating and/or isolated from the layer (14, 23) of sinterable electrical connection material; - realising an electrical and mechanical coupling between the membranes and the supports by placing the first workpiece on top of the second workpiece in the furnace, with the first main face of the first workpiece facing the second main face of the second workpiece, and sintering until the layers of sinterable electric connection material (14, 23) melt in a reflow process becoming a single layer of material and until the layers of sinterable mechanical connection material (13, 21) melt in a reflow process becoming a single layer of material, the layers of sinterable electrical connection material (14, 23) and the layers of sinterable mechanical connection material (13, 21) undergoing to said reflow together in a single step in said sintering furnace; - the pressure sensor, together with other pressure sensors, is obtained by dividing into parts the workpiece deriving from the electrical and mechanical coupling between the first and the second semi-finished workpieces (1, 4). - providing a first sheet-like workpiece having a first main face and a second main face, the first workpiece defining a plurality of membranes;
