PROBLEM TO BE SOLVED: To provide a highly reliable pressure sensor at low cost by forming parts constituting the pressure sensor of resin as much as possible. SOLUTION: A metallic pressure introduction cylinder 2 is set which has a pressure introduction hole 12 for introducing a pressure of a medium to be measured. The pressure sensor detects the pressure of the medium by a sensor element 5 arranged in a state to receive the pressure of the medium introduced from the pressure introduction hole 12. The pressure sensor has a housing 3 of synthetic resin to which the pressure introduction cylinder 2 is inserted and in which the sensor element 5 is stored.
