PROBLEM TO BE SOLVED: To provide an oscillation detecting sensor for determining size of oscillation by an amount of output charge and detecting not small oscillations but only large oscillations.SOLUTION: An oscillation detecting sensor device includes a sensor part and a recording part. The sensor part includes: an oscillation power generation device for generating power by outside oscillation; a power storage device for storing charges generated by the oscillation power generation device through power generation; a leak device for leaking the charges stored by the power storage device to the ground; and a power storage determination device for determining an amount of charge stored in the power storage device and, when the amount of charge is larger than a prescribed amount, supplying the recording part with charges stored in the power storage device. |
