PROBLEM TO BE SOLVED: To provide a compact power generation device that outputs DC voltage.SOLUTION: A power generation device includes a device substrate 20, a power generation section 24, and a rectifying section 28. The device substrate 20 has: a support portion 21; a cantilever portion 22 that is supported swingably on the support section 21; and a weight portion 23 that is provided at a leading end, of the cantilever portion 22, opposite to a side of the support portion 21. The power generation section 24 is provided in the cantilever portion 22, and generates AC voltage in response to vibration of the cantilever portion 22. The rectifying section 28 is provided in the weight portion 23, and rectifies the AC voltage generated in the power generation section 24. |
