摘要： PROBLEM TO BE SOLVED: To provide a pressure sensor having a structure preventing corrosion between a housing and a metallic diaphragm which are made of different metals.
SOLUTION: The metallic diaphragm 34 is connected to the housing 30 side, wherein the connection part is placed inside an O-ring 43. Thereby, if water penetrates through a caulking section 36, the water is sealed by the O-ring 43 and does not reach the connection part between the metallic diaphragm 34 and the housing 30. Consequently, even when the housing 30 and the metallic diaphragm 34 are made of different metals, the occurrence of corrosion therebetween caused by a contact potential difference is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a sensor device for semiconductor physical quantities with a sensor circuit, capable of preventing changes in a GND voltage used for a circuit reference voltage from occurring, caused by a parasitic impedance of noise GND wiring, when high-frequency noise is projected on or injected in a sensor chip.
SOLUTION: GND wiring G1 being the GND for the circuit reference voltage and GND wiring G2 that is the GND for a noise filter are separated from each other so as to make up separate arrangements. Furthermore, single-point ground is made, such that these GND wirings G1, G2 are connected to a bonding wire 5c via a GND pad 2b. As a result, the voltage changes in the GND wiring G1 that is the GND for the circuit reference voltage, is prevented from occurring, based on the parasitic impedance of the GND wiring G2 that is the GND for the noise filter, even when high-frequency noise is irradiated on or injected in the sensor chip 400. As a result, a signal, having a wrong output, can be prevented from existing.
