To provide a guard fence hard to be fouled 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.
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 the surface of a base material. Consequently, hydrophilic attachments are made not to become attached to the part showing 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. Consequently, neither a hydrophilic attaching matter nor a hydrophobic attaching matter is fastened on a surface of a member, and it is possible to maintain the surface in a clean state.
