摘要： A pressure detecting device includes: a resonator whose oscillation frequency varies depending on a pressure; a first oscillation circuit that oscillates the resonator and outputs a signal of a frequency corresponding to the pressure; an AT-cut quartz crystal resonator; a second oscillation circuit that oscillates the AT-cut quartz crystal resonator and outputs a reference clock signal; a measuring unit that measures the reference clock signal by the use of a reciprocal counting method; a temperature detecting unit that detects a temperature of the resonator; and a storage unit that stores coefficients of a first approximating polynomial for calculating a first correction value used to compensate for a frequency-temperature characteristic of the measuring unit, wherein the frequency-temperature characteristic of the value measured by the measuring unit includes a frequency-temperature characteristic of the AT-cut quartz crystal resonator and a frequency-temperature characteristic of the resonator.

摘要： A pressure sensor includes: a diaphragm having a pressure-receiving portion receiving a pressure and a thick portion adjacent to the pressure-receiving portion; and a pressure sensitive element having a first and a second ends facing each other. The pressure sensitive element extends in a direction intersecting the thick portion and the first end of the pressure sensitive element is bonded to a pressure-receiving surface of the pressure-receiving portion, and a central portion of a portion at which the pressure-receiving portion and the first end are bonded is positioned at a side closer to the second end of the pressure sensitive element than a center of the pressure-receiving portion.
