PROBLEM TO BE SOLVED: To provide a pressure detector which does not change an output signal of an amplifier unit mounted to a circuit board even when the circuit board is deflected. SOLUTION: The detector has a semiconductor type pressure sensor 3, an amplifier unit 5 for amplifying an electric signal output from the pressure sensor 3, a circuit board 2 where the pressure sensor 3 and amplifier unit 5 are arranged, and a housing 1 where a boss body (mount part) 11 is set to place the circuit board 2. The circuit board 2 is provided with a free end part 13 not supported by the boss body 11 and the amplifier unit 5 is mounted to the free end part 13.
