A vibration-based power generator is provided that has high power generation efficiency by maximizing a movable range of a permanent magnet. A vibration-based power generator 1 includes a first housing 11 and a second housing 21. The first housing 11 is connected to electrode terminals 12a and 12b, which are conductively connected. The first housing 11 houses a power generation unit 13 that includes a tubular shaped member 14, a coil 15, and a permanent magnet 16. The second housing 21 is connected to a positive terminal 22a and a negative terminal 22b. The second housing 21 houses a rectifier portion 23 and an electricity storage portion 24. Alternating electric current is generated in the coil 15 due to the permanent magnet 16 moving reciprocally inside the coil 15. The alternating current is rectified by the rectifier portion 23 and is stored in the electricity storage portion 24. The electrode terminal 12b and the positive terminal 22a are shorted. The positive terminal 22a and the electrode terminal 12a have the same electric potential. The electric current stored in the electricity storage portion 24 is output to the outside via the electrode terminal 12a and the negative terminal 22b. |
