Pressure sensor

A pressure sensor comprising:

• a substrate;
• a differential pressure diaphragm, having at least a first edge, provided in a center portion of the substrate;
• a single pair of first and second differential pressure gauges provided only on the first edge of the differential pressure diaphragm,
• the first differential pressure gauge formed along a radial direction relative to a center of the differential pressure diaphragm, and
• the second differential pressure gauge formed along a circumferential direction, which is perpendicular to the radial direction, and provided in a vicinity of the first differential pressure gauge on the first edge of the differential pressure diaphragm;
• a static pressure diaphragm disposed between an edge portion of the substrate and one of the edges, other than the first edge, of the differential pressure diaphragm, provided to an outside of the differential pressure diaphragm.
