To provide a sensor element capable of preferably detecting three-dimensionally acting external force.

There are provided: an elastic member E capable of being compressed or stretched by the external force F received from an object OB; a resistive element R having the electric resistance value increased/decreased when receiving the external force F and deformed; and a support member C4 disposed inside the elastic member E or on the surface thereof and capable of supporting the resistive element R at a prescribed position.
