A pressure sensor is provided to absorb elastic displacement by the winding density difference of the contact terminal and maintain the electrical connection with the circuit board. A pressure sensor(80) includes a contact terminal(94) contacting a circuit board of an electronic control unit. The contact terminal consists of a first coil spring section(94a) contacting the circuit board of the electronic control unit, and a second coil spring section(94b) extended from the first coil spring section to be connected to the pressure sensor body. Both the winding density and spring constant of the first coil spring section are greater than those of the second coil spring section. The winding diameter of the first coil spring section is less than that of the second coil spring section.
