摘要： A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

摘要： A detector provided on a flat portion of a diaphragm includes a plurality of strain gauges, resistor element connectors connecting adjacent ones of the strain gauges, and an electric conductor covering a part of the resistor element connectors. First linear portions and second linear portions of the resistor element connectors exposed from the electric conductor are orthogonal to the edges of the electric conductor extending across the first linear portions and the second linear portions. Even when a pattern of the resistor element connector and a pattern of electric conductor are misaligned in X direction or in Y direction, an area of the resistor element connector exposed from the electric conductor does not change.
