A sensor element capable of appropriately detecting an external force operating three-dimensionally is provided. The sensor element includes an elastic member which can be compressed or expanded by an external force received from an object, a resistance element whose electric resistance value rises or falls when deformed by the external force, and a support member arranged inside or on the surface of the elastic member and capable of supporting the resistance element disposed at a predetermined position. The sensor element is applied to an object movement control device and an object judgment device.
