Abstract:
     A load detecting device includes a sensor element including a function for generating and detecting a vibration within a single element, the sensor element converting a load or an acceleration into a detection signal, a driving portion for outputting a driving signal for vibrating the sensor element, a vibration detecting portion for extracting the detection signal from the sensor element and for detecting a vibration characteristic value of the sensor element, a wiring for electrically connecting the sensor element, the driving portion and the vibration detecting portion to one another, and for transmitting a superimposed signal constituted by superposition of the driving signal from the driving portion and the detection signal from the sensor element, and a calculating portion for calculating one of or both of a load and an acceleration applied to the sensor element based on the vibration characteristic value from the vibration detecting portion.
