PROBLEM TO BE SOLVED: To provide a power-generation rod capable of obtaining stable power.SOLUTION: A power-generation rod 1000 includes: a shaft part 10; and a power generation part 100 externally mounted on the shaft part 10. The power generation part 100 includes: at least one magneto-striction rod 102a constituted of a magneto-striction material: a coil 103a which is wound around the magneto-striction 102a rod and generates current by change in magnetic flux of the magneto-striction rod 102a; and yokes 101a and 101b which support both ends of the magneto-striction rod 102a constituted of a magnetic substance. Power is generated by vibration of high frequency generated by impact given to the tip of the shaft part 10. |
