摘要： There is provided a thermal transfer sheet having satisfactory peelability when a transfer layer is peeled off without being affected by a peeling environment when the transfer layer is peeled off.
A thermal transfer sheet 100 includes a substrate 1 and a transfer layer 10 provided on one surface of the substrate 1, in which the peeling force in a stable period is in the range of 4.6 g/cm or more and 23 g/cm or less when the transfer layer 10 is peeled off at a peeling temperature in the range of 30° C. or more and 70° C. or less and at a peeling angle of 90° while the surface of the transfer layer 10 on the side opposite to the substrate 1 is made to serve as a peeling interface.-
