PROBLEM TO BE SOLVED: To provide a power generating device, and the like, which can use piezoelectric effects of a piezoelectric material so as to generate a high voltage without causing an increase in size and that can also prevent damage to a deformable member, and suppress a deterioration in durability of the deformable member, during transportation of the power generating device.SOLUTION: A power generating device 100 includes: a beam (deformable member) 104 that is deformed in switched directions; a piezoelectric member 108 provided in the beam 104; a pair of electrodes 109a and 109b provided in the piezoelectric member 108; an inductor L that is provided between the pair of electrodes 109a and 109b and forms a resonance circuit together with a capacitance component C0 of the piezoelectric member 108; a switch SW connected in series to the inductor L; a vibration detection section 140 that detects a vibrational state of the beam 104; a control circuit (control section) 112 that puts the switch SW in a conduction state for a predetermined period of time (a first period of time) on the basis of the detection result of the vibration detection section 140; and a short-circuit section 130 that forms a short circuit between the pair of electrodes 109a and 109b. The short-circuit section 130 is provided so as to release the short circuit between the pair of electrodes 109a and 109b before the power generating device 100 starts a power-generating operation. |
