PROBLEM TO BE SOLVED: To provide a tacky adhesive sheet which beautifully maintains appearance and improves workability in recycling treatment and the mechanical characteristics of recycling materials. SOLUTION: The tacky adhesive sheet 1 has a tacky adhesive sheet base material 1a, tacky adhesive 1b of the tacky adhesive sheet base material, ink layer 1c, tacky adhesive 1e of laminated materials and the laminated materials 1d and is pasted to a resin adherend 2 to display image information, in which the tacky adhesive sheet holds down the gas produced from the resin adherend 2 by the interaction of bending rigidity and the tacky adhesive power to the resin adherend 2 and therefore prevents the tacky adhesive sheet 1 from bulging and floating. Materials 1a to 1d composing the tacky adhesive sheet 1 are formed of a thermoplastic resin having compatibility with the resin adherend 2 and therefore the need for peeling the tacky adhesive sheet 1 in the recycling treatment is eliminated.
