A pressure sensor includes a case with an air passageway having a first opening leading to an inside of the case and a second opening leading to an outside of the case, pressure sensing means that is placed inside the case and includes a pressure sensing surface for detecting pressure, and a breathable filter that is provided with the air passageway to cover at least one of the first and second openings. The pressure sensing means is fixed to the case through mounting means that allows the pressure sensing means to be spaced from the case to prevent stress that is applied to the pressure sensing means by the case.
