A pressure sensor comprising two parts connected with one another via an active braze joint manufactured by active hard soldering, or brazing, with an active hard solder, or braze, especially a pressure contactable, pressure-dependently elastically deformable, measuring membrane, especially a ceramic measuring membrane, and a platform, especially a ceramic platform, which are connected by an active braze joint connecting an outer edge of the measuring membrane (which covers a pressure chamber with an outer edge of an end of the platform facing the measuring membrane, whose measuring characteristics are improved in that the active braze joint has a coefficient of thermal expansion dependent on the dimensions of the active braze joint and on the materials of the parts and matched to a coefficient of thermal expansion of at least one of the parts, especially the measuring membrane.
