A thermal transfer sheet capable of accurately removing a transfer layer without being affected by conditions when the transfer layer of an intermediate transfer medium is removed by a peel-off layer. In a thermal transfer sheet having a peel-off layer, the thermal transfer sheet is provided with a primer layer and a peel-off layer in this order on a substrate, and the primer layer has (1) a primary particle diameter. Inorganic particles derived from sol-based inorganic particles having a particle size of 200 nm or less, (2) scale-like inorganic particles, (3) a polyvinylpyrrolidone resin having a glass transition temperature (Tg) of 60 ° C. or higher, and (4) a glass transition temperature (Tg). (5) a polyurethane resin having a heat melting temperature of 100 ° C. or higher, (6) a resin obtained by curing a thermoplastic resin having a glass transition temperature (Tg) of 40 ° C. or higher, (7 The above-mentioned problem is solved by including at least one of resins obtained by curing a polyvinyl alcohol resin.
