To provide a thermosensitive recording self-adhesive sheet, in which neither formation of color, nor foaming, nor lifting, nor flaking develops at at least 150°C and not more than 280°C, which is excellent in workability and storage stability and which forms colors ranging from light color to highly contrast black color by controlling the quantity of heat given by a thermal head or a stimulatedly emitted light amplified light wave.

In the thermosensitive recording self-adhesive sheet, a self-adhesive layer is formed on at least one side of a sheet-like thermosensitive recording layer comprising a composite metal oxide containing molybdenum and copper and its carrier. Alternatively, in the thermosensitive recording self-adhesive sheet, a thermosensitive recording layer comprising a composite metal oxide containing molybdenum and copper and its carrier is formed on at least one side of a resin sheet and a self-adhesive layer is formed at least on either the thermosensitive recording layer or the resin sheet.
