PROBLEM TO BE SOLVED: To prevent color development of a heat-sensitive recording material at the time of heat activation of a heat-activatable pressure-sensitive adhesive, to have a sufficient adhesive force to various adherends, and to prevent blocking during storage, and does not require release paper. Provide a label. In a thermosensitive recording medium having a thermosensitive coloring layer containing a colorless or electron donating leuco dye and an electron accepting developer on a support, a thermoactive pressure-sensitive adhesive layer is provided on the opposite side of the thermosensitive recording layer. It is a thermosensitive recording medium label characterized by being provided, and an excellent effect is manifested particularly by providing a thermally active adhesive layer having a thermal activation temperature of 50 to 100 ° C.
