An electrically-heated window sheet material includes a heatable transparent conductive film, and multiple bus bars for supplying electricity to the transparent conductive film. The multiple bus bars include a left bus bar connected to a left edge of the transparent conductive film, and a right bus bar connected to a right edge of the transparent conductive film. The transparent conductive film includes a band-shaped first region interposed between the left bus bar and the right bus bar, a band-shaped second region interposed between the left bus bar and the right bus bar, and multiple openings provided in the first region. The first region, by including the opening having a vertical dimension that is greater than or equal to a predetermined value, includes a frequency selective surface that allows a horizontally polarized electromagnetic wave of a frequency band of a predetermined frequency to be transmitted. The multiple openings are arranged so that a current flowing in the first region from one of the left and right bus bars to the other of the left and right bus bars is bypassed at least once by the openings.
