A planar heating element includes an insulating resin film and a heating portion that includes a conductive circuit on the insulating resin film. The insulating resin film includes missing portions penetrating the insulating resin film, surrounding a point on the insulating resin film, and including one or both of openings and recesses. The openings are disposed within the conductive circuit and outside of a circular region of a radius centered at the point. The recesses are recessed toward an inside of the insulating resin film and located on an outer edge of the insulating resin film.
