Abstract
There is provided a method for producing a piezoelectric element, which allows for forming a columnar microstructure with a small width and a high aspect ratio. The method is intended to produce a piezoelectric elementincluding a three-dimensional structure grouphaving a plurality of the three-dimensional structuresandformed in a plate-like or columnar shape with a width of 30 μm or less and a height of 80 μm or more. The production method includes a first process of fabricating a plurality of plate-like or columnar precursor shapeson a bulk materialformed of a Pb-based piezoelectric material, and a second process of reducing the width of the precursor shapesto a predetermined value using an etching liquid.
