A plate for an electro-thermal window includes a transparent conductive film that can be heated, and multiple bus bars that feed power to the transparent conductive film. The multiple bus bars include a left bus bar connected to a left side edge part of the transparent conductive film and a right bus bar connected to a right side edge part of the transparent conductive film. The transparent conductive film is divided into multiple regions by a slit that is continuously or discontinuously formed from the left bus bar to the right bus bar. The multiple regions include a first region and a second region. A distance between the left bus bar and the right bus bar of the first region is shorter than a distance between the left bus bar and the right bus bar of the second region. A width of the first region in a direction orthogonal to the slit is shorter than a width of the second region in the direction orthogonal to the slit.
