PROBLEM TO BE SOLVED: To provide a sensor device capable of securely attenuating a high frequency vibration which causes resonance and capable of being manufactured inexpensively. SOLUTION: In the sensor device 1 equipped with a G sensor 2 for outputting an electric signal according to physical displacement of a sensing part and a casing 3 on which the G sensor 2 is to be loaded, since peripheral of G sensor 2 is primarily formed of a first resin material capable of attenuating high frequency vibration, the high frequency vibration which causes resonance securely attenuates and correct detection output of collision and vibration can be performed without being affected by resonance. Since a secondary forming part 3b which is secondary-formed with a second resin material being harder than the first resin material is formed around a primary forming part 3a, it is possible to prevent the casing 3 from being broken by external shock.
