Abstract
The invention provides a load sensor which is driven by a low electric power consumption, can measure at a high precision, and has a high reliability without being broken. The load sensor is structured such that a detection rod for detecting a strain is provided in an inner portion of a hole formed near a center of a pin via a shock relaxation material and a semiconductor strain sensor is provided in the detection rod, in a load sensor detecting a load applied to the pin from a strain generated in an inner portion of the pin.
