POWER GENERATION MODULE

A power generation module includes a power generation element having a magnetic core elongated in one direction and a coil wound around the magnetic core, an induction yoke part having a first induction yoke contacting one end of the magnetic core in a longitudinal direction of the magnetic core and made of a magnetic material and a second induction yoke contacting the other end of the magnetic core in the longitudinal direction and made of a magnetic material, and a magnet part that is relatively displaceable relative to the power generation element in a direction perpendicular to the longitudinal direction. The magnet part has a first magnet and a second magnet arranged in the displacement direction. The first magnet has an N-pole part and an S-pole part arranged in the longitudinal direction. The second magnet has an N-pole part and an S-pole part arranged in the longitudinal direction. The N-pole part of the first magnet and the S-pole part of the second magnet face each other in the displacement direction, while the S-pole part of the first magnet and the N-pole part of the second magnet face each other in the displacement direction. When the magnet part is located in a first position relative to the power generation element, the N-pole part of the first magnet faces the first induction yoke, while the S-pole part of the first magnet faces the second induction yoke. When the magnet part is located in a second position relative to the power generation element, the S-pole part of the second magnet faces the first induction yoke, while the N-pole part of the second magnet faces the second induction yoke.
