Summary:A power generation device includes a holder 101 with a natural frequency of fA, and two or more vibration energy harvesting elements 105 held by the holder 101 and having natural frequencies different from each other. Out of the vibration energy harvesting elements 105, one has the lowest natural frequency fBminsatisfying the following Expression 1, and another one has the highest natural frequency fBmaxsatisfying the following Expression 2:fBmin≥0.925−2.5N/100fAandfBmax≤1.075+2.5N/100fAwhere N is the number of the vibration energy harvesting elements 105.
