ABSTRACT:
An object of the present invention is to provide a transparent noise-barrier wall which is slow to foul, easy to clean even when fouled, and capable of maintaining these effects over a long period of time. The transparent noise-barrier wall has brookite titanium dioxide substantially existing on the surface. The titanium dioxide particles preferably contain about 20% by mass or more of brookite titanium dioxide.
