Abstract
A displacement magnifying mechanism includes a base portion serving as a substrate; a first attachment portion and a second attachment portion which are provided on a surface on one side of the base portion; a first piezoelectric element and a second piezoelectric element of which one ends are attached to the first attachment portion and the second attachment portion; an operating portion which is connected to the other ends of the first piezoelectric element and the second piezoelectric element and generates a displacement due to expansion and contraction of the piezoelectric element; and a link portion which is disposed at the center between the first piezoelectric element and the second piezoelectric element, links the operating portion and the base portion, and is made of a material having a higher Young's modulus than that of the first piezoelectric element and the second piezoelectric element.
