The film material 2 which is a main part of the reflection plate is, for example, a reflection material such as silver or gold is applied to the surface of a canvas having a length of about 1.5 m and a width of about 75 cm, and an elastic body 4 is formed on the back surface to have a diameter of about 70 cm and a width of 5 mm. A thick cloth tape with a width of about 15 mm containing a steel ribbon inside
The sewn pieces are separated from each other to form a substantially oval reflector including the elastic body 4 as a peripheral portion. The elastic body 4 is formed into a figure of eight by twisting it with both hands.
