Document Type and Number:
Japanese Patent JP7385178
Kind Code:
B2
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.
