Abstract
There are included: an oscillating member that includes a tough layer and a magnetostrictive layer stacked above the tough layer and formed of a magnetostrictive material, the tough layer formed of a tough material having a tensile strength higher than that of the magnetostrictive material; a supporting member to which the oscillating member is attached to be able to oscillate in the thickness direction; a magnetic field applying member that applies a magnetic field to the magnetostrictive layer; and a coil that is disposed around the magnetostrictive layer.

A power generating device, comprising:
- an oscillating member, the oscillating member comprising:
- a tough layer, and
- a magnetostrictive layer that is stacked above the tough layer and is formed of a magnetostrictive material, the tough layer formed of a tough material having a tensile strength higher than that of the magnetostrictive material;
- a supporting member to which the oscillating member is attached to be able to oscillate in the thickness direction;
- a magnetic field applying member that applies a magnetic field to the magnetostrictive layer;
- and
- a coil that is disposed around the magnetostrictive layer,
- wherein a recessed portion is formed in a surface of the supporting member and the oscillating member projects above the recessed portion at the tip side of the oscillating member.
