Abstract
A pressure sensor for detecting pressure includes: a metallic diaphragm for receiving the pressure; four strain gauges providing a Wheatstone bridge, wherein each strain gauge outputs an electric signal corresponding to deformation of the diaphragm when the diaphragm is deformed by the pressure; and four semiconductor chips corresponding to four strain gauges, wherein each strain gauge is disposed in the semiconductor chip. Each semiconductor chip is mounted on the diaphragm.
