ABSTRACT:
A pressure detection device includes a sensing part that is provided at one end portion of the housing to output an electrical signal responsive to an applied pressure, a circuit part that is provided at an other end portion of the housing to process the signal from the sensing part, and a flexible printed board provided in the housing between the sensing part and the circuit part. Furthermore, the flexible printed board has a first end portion electrically connected to the sensing part at a first connecting part, and a second end portion electrically connected to the circuit part at a second connecting part. In the pressure detection device, the flexible printed board is shaped between the first and second end portions to relieve a stress applied to the connecting parts.
