PROBLEM TO BE SOLVED: To provide a road mirror hard to be fouled and on which droplets are hard to be attached by forming a surface layer having structure microscopically dispersed both of a part showing a hydrophilic property where photocatalytic oxide particulates are exposed to make contact with outside air and a part showing water repellency where water repellent fluorine contained resin is exposed to make contact with the outside air on a surface of a base material and a contact angle with water of which is more than a specified angle. SOLUTION: A surface layer having structure microscopically dispersed both of a part showing a hydrophilic property and a part showing water repellency due to water repellent fluorine contained resin is formed on a surface of a base material, hydrophilic attachments are made not to become attached to the part showing the water repellency, and hydrophobic attachments are made not to become attached to the part showing the hydrophilic property. Additionally photocatalytic oxide particulates are made to exist on the part showing the hydrophilic property, and the hydrophilic property of the part showing the hydrophilic property is maintained in accordance with light excitation. Additionally, it is made hard for droplets to attach on it by making a contact angle at 90 deg. or more. Consequently, the surface is maintained in a clean state, it becomes hard for the droplets to attach on it, and it is possible to improve safety operability of a travelling car. |
