An embossed groove by heat press emboss forming was filled with a part of the pressure-sensitive adhesive layer, a residual rate of the pressure-sensitive adhesive layer ranges between 10% and 50% inclusive, and a fall time of the pressure-sensitive adhesive layer ranges between 10 hours and 150 hours inclusive.
