To provide a sensor device capable of preventing its destructive withstand pressure from lowering, while enhancing the sensitivity.

The sensor device 1 comprises a frame part 10, a movable part 20 and a carbon nanotube element 31 bridging across the frame part 10 and the movable part 20. Furthermore, the sensor device 1 comprises a corrugated part 40 which is made corrugated and connecting the frame part 10 to the movable part 20, and is configured to detect a physical quantity of an object to be detected by using the variation in the resistance value of the carbon nanotube element 31.
