Abstract
Provided is a thermal transfer sheet capable of repressing residue that accumulates before insertion of a heating element of the thermal head. In the thermal transfer sheet, a heat-resistant lubricating layer is formed on a surface of the substrate, wherein the heat-resistant lubricating layer includes one or more of layers which include a back face layer, the back face layer is arranged at a position farthest from the substrate, at least one layer which composes the heat-resistant lubricating layer includes a binder resin and organic minute particles which each has a polygonal shape, and a portion of surfaces of the organic minute particles protrude from a surface of the back layer.
