A diaphragm-type pressure sensing apparatus includes a pressure sensor having a diaphragm for converting pressure into an electrical signal, a circuit board for processing the electrical signal, and a housing in which the pressure sensor and the circuit board are sealed. The pressure sensor is bonded to the housing and sandwiched between the circuit board fixed to the housing and the housing. This structure reduces compressive stress applied to the pressure sensor and the circuit board so that accuracy of the pressure sensing apparatus can be improved.
