PROBLEM TO BE SOLVED: To provide a pressure detector for measuring engine supply air pressure and atmospheric pressure. SOLUTION: An airtight chamber 32 and a non-airtight chamber 34 of a case 30 have a supply air pressure sensor chip 20A and an atmospheric pressure sensor chip 20B. By introducing the supply air pressure of an engine to the airtight chamber 32 via a port 42, the supply air pressure is measured by the supply air pressure sensor chip 20A, and atmospheric pressure is introduced into the non-airtight chamber 34, thus measuring the atmospheric pressure by the atmospheric pressure sensor chip 20B.
