  By the way, all of these conventionally proposed snow melting devices have a structure in which a pipe or the like is buried in a place where the snow is desired to be melted (in concrete or asphalt), so that only a predetermined place (a place where piping is provided) melts snow. In addition, the installation cost is high, and a considerable amount of time is required for installation.

  Therefore, conventionally, a snow melting device having a structure including a snow melting panel having a heat generating structure has been proposed.
