Is transmitted to the soil G along the longitudinal direction of the soil. In a normal case, the direction of the light beam rarely coincides completely with the longitudinal direction (axial direction) of the rod-shaped body 1, and is transmitted in a state inclined with respect to the longitudinal direction as shown in FIG. Then, in the tapered portion 1c, each time the light beam is repeatedly reflected, the light beam enters a state in which the light beam gradually approaches a right angle to the surface, and the light beam is easily emitted from the surface to the outside.

触媒２が光触媒反応を発生し易くなる。When the photocatalyst 2 is carried in the concave portion 1b of the rod 1, the rod 1 is stabbed or driven into the soil G by utilizing the fact that the rod 1 is pile-shaped. The resistance of the photocatalyst 2 at the concave portion 1b is liable to cause a photocatalytic reaction because the resistance of the photocatalyst 2 to the soil G is small and the light is difficult to fall off, and the light beam crosses the wall of the concave portion 1b and is easily branched.
