Claim:
1. A differential pressure sensor comprising: a sensor chip having: a sensor housing having: the sensor chip, between a first inner wall surface and a second inner wall surface of the sensor chamber, is joined by a first adhesive agent layer between one face of the sensor chip and the first inner wall surface of the sensor chamber and joined through a second adhesive agent layer between other face of the sensor chip and the second inner wall surface of the sensor chamber; the first adhesive agent layer is an adhesive agent layer that has a Young's modulus that is smaller than the Young's modulus of a material that structures the sensor diaphragm; and the second adhesive agent layer is an adhesive agent layer that has a Young's modulus that is smaller than the Young's modulus of the material that structures the sensor diaphragm and larger than the Young's modulus of the first adhesive agent layer.
