Disclosed is a pressure sensor 1 for a vehicle including a sensing element 10 for measuring the pressure of brake fluids in fluid passages, a sensor housing 20 for accommodating the sensing element 10, and contact probes 30 that are electrically connected to the sensing element 10 and an electronic control unit 300 (control unit). Each contact probe 30 includes a sleeve 31, a coil spring 32 (elastic member) housed in the sleeve 31, the rod 33 inserted into the sleeve 31. The sleeve 31 is connected to the sensing element 10 in a state that the sleeve 31 is fixed in the sensor housing 20, and the rod 33 is pressed to the electronic unit 300 by pressing force of the coil spring 32.
