PROBLEM TO BE SOLVED: To provide a pressure sensor capable of detecting and outputting two kinds of physical quantities, temperature and pressure, with a simple constitution. SOLUTION: The pressure sensor 10 comprises a pressure detecting element 50 for detecting pressure of a fluid to be detected and outputting a primary pressure signal, and a temperature detecting element 55 for detecting ambient temperature of the pressure detecting element 50 and outputting a temperature signal. The pressure sensor 10 generates a secondary pressure signal temperature-compensated with respect to the fluid to be detected based on the primary pressure signal from the pressure detecting element 50 and the temperature signal from the temperature detecting element 55. The pressure sensor 10 further comprises a pressure signal output terminal 61 for outputting the secondary pressure signal to the outside, and a temperature signal output terminal 62 for outputting the temperature signal to the outside.
