To provide a thermal transfer sheet in which there is no unevenness in light and shade of a printed matter and transfer sensitivity in high-speed printing is high, and which can reduce dye used in a dye layer by obtaining a thermal transfer sheet where the size and the number thereof are limited in a specified range, as to the form of particles which exist in a heat-resistant lubricating layer provided on a substrate.
In the thermal transfer sheet in which one side of the substrate 1 is provided with a heat-resistant lubricating layer 2 and an undercoat layer 3 and a dye layer 4 are formed in order on the other side of this substrate 1, the undercoat layer 3 consists of a layer which includes a water-soluble polymer, and the heat-resistant lubricating layer 2 consists of a layer which includes at least resin and inorganic particles, and particles of 100 μm2 or over in area are 500 pieces/mm2, in particles which correspond to inorganic particles or an aggregate of inorganic particles observed from the side of the heat-resistant lubricating layer 2.
