[PROBLEMS] To provide a pressure sensor device which not only receives a pressure change and a temperature change, but also has a drastically improved durability life even in a use environment where it is exposed to an atmosphere such as gasoline vapor, steam, acidic exhaust gas, and the like. To provide. A pressure comprising a housing, a sensor chip housed inside the housing, a sensor chip fixed to a pedestal having a back surface adhered and fixed to the bottom surface of the housing via an adhesive, a terminal, and a bonding wire connecting the sensor chip and the terminal. Sensor device. At least the top of the terminal is coated with a fluorine-based adhesive, and the same type of fluorine-based gel as the fluorine-based adhesive is filled so that the coated terminal, the sensor chip, and the bonding wire are all buried. Be done. |
