The heat-fusible ink layer comprises a carbon black having toluene-coloring transmittance of 60% or more, and, therefore, there is provided a thermal transfer sheet containing a heat-fusible ink layer having an uniform thickness and being capable of providing printed letters improved in blackness and durability such as solvent resistance.
