Abstract
Task of the present invention is to provide a power-generating magnetostrictive element and a magnetostrictive power generation device equipped with the same, which are capable of achieving the same or a greater magnetostrictive power generation amount compared to conventional technology while employing materials lower in cost compared to conventional magnetostrictive materials. The task is achieved by providing a magnetostrictive element comprising a magnetostrictive part formed of an electromagnetic metal sheet. The present invention also provides a power-generating magnetostrictive element and a power-generating magnetostrictive element having high voltage with little variation. The task is achieved by providing a magnetostrictive element comprising a magnetostrictive part formed from a magnetostrictive material and a stress control part formed from an elastic material, the materials each having a Young's modulus and a sheet thickness simultaneously satisfying specific relationships.
