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 element 102 including a three-dimensional structure group 20 having a plurality of the three-dimensional structures 21 and 321 formed 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 shapes 82a on a bulk material 81 formed of a Pb-based piezoelectric material, and a second process of reducing the width of the precursor shapes 82a to a predetermined value using an etching liquid.

Abstract: Provided is an optical element having particularly excellent salt water resistance and capable of exhibiting a photocatalytic effect. An optical element 100 is obtained by forming a multi-layer coating MC having two or more layers on a glass substrate GL that is an optically-transparent base plate. The multi-layer coating MC has at least one low-refractive-index layer L and at least one high-refractive-index layer H, and a topmost layer 10 farthest from the glass substrate GL is the low-refractive-index layer L. The high-refractive-index layer H adjacent to the topmost layer 10 is a functional layer 20 containing, as a main component, a metal oxide having a photocatalytic function. The topmost layer 10 has a plurality of pores 30 that partially expose a surface of the functional layer 20.

Abstract: A functional film provided on a base material and having a fine uneven structure on its surface of the functional includes a coating. The coating is a coating film or a coating layer of the fine uneven structure. The coating is on a surface of the base material or a constituent layer and covers at least a bumpy portion or an entire surface of the base material. The fine uneven structure includes bumps and dents whose mutual positional relationship and shape have randomness with no regularity in terms of identity or periodicity and does not generate diffracted light.
