Abstract: A sheet includes a conductive film, and bus bars including an upper and lower bus bars connected to upper and lower sides of the conductive film. The conductive film includes a recess, a first region between the upper bus bar and the lower bus bar, a second region that is another region between the upper and lower bus bars, and openings in the first region. The upper or lower bus bar is formed along a side of the conductive film including the recess. The first region is between a bus bar at which the recess is positioned and another bus bar facing the recess. A distance between the upper and lower bus bars is shorter in the first region than in the second region. The openings are formed in an upper or a lower part of the first region on a side of the another bus bar.

Abstract: A vehicle window glass includes a glass plate; a dielectric body; a conductive body arranged between the glass plate and the dielectric body; and an antenna. The conductive body includes a concave portion is provided. The concave portion is interposed between a first vertical edge side and a second vertical edge side extending downward from an upper outer edge of the conductive body. The antenna includes a feeding portion and an antenna element. A part of the feeding portion and a part of the antenna element are located in a region of at least one of a region interposed between a first extension line and a second extension line extended upward from the first vertical edge side and the second vertical edge side, and of the concave portion. The feeding portion is arranged closer to the first vertical edge side than a lower end of the concave portion.
