Abstract: A pressure detector includes a passage casing, a fixing body, a sensing member, a sealing member, and a power supply member. The passage casing and the fixing body form a receiving space where the sensing member is disposed in. The sealing member is filled into the rest of the receiving space and separates the sensing member from the fixing body, and prevents a fluid to be measured coming from the chamber from leaking to outside space. The circuit board of the sensing member is protected from contacting the fluid to be measured directly. Thus, the accuracy of measuring pressure is improved, and the lifetime of the pressure detector is lengthened.
