PROBLEM TO BE SOLVED: To prevent the occurrence of the appearance in which the periphery of the opening section of a main body appears to be a picture frame and to eliminate a low class appearance of the body by providing a thickness part at the position, where a flange overlaps with the body, and forming a reflection surface on the thickness part. SOLUTION: When a window material 10 is fitted to an opening section 7 of a panel 2 from a second opening section 7b, the portion, which overlaps with a thickness part 13 of a main body 11, is positioned at the periphery of the section 7 and a side edge section 12a of a flange 12 is placed opposite to the side peripheral surface of the section 7b. Thus, when the part 13 of the material 10 is seen from the right front, it is reflected by a reflection surface 14, the inner peripheral surface of the section 7b is seen as the virtual image of the edge of the body 11, i.e., a prescribed color widthγfrom the opening width and the black color, which is the color of the panel 2, is seen as the color of the body 11. Thus, the portion, which overlaps with the part 13 among the body 11, is not viewed as a picture frame.
