Abstract
A heat delivery element for a shaving razor with a face plate having a skin contacting surface and an opposing inner surface. A heater having a heater track is positioned between an upper dielectric layer and a lower dielectric layer. A heat dispersion layer having a lower surface directly contacts the inner surface of the face plate. An upper surface of the heat dispersion layer directly contacts the lower dielectric layer of the heater. The heat dispersion layer has graphite foil compressed by 20% to 50% of an original thickness.
