Abstract: The present invention provides an adhesive sheet for attaching to a plasticized vinyl chloride resin article such as a blood bag made of a plasticized vinyl chloride resin, and having a center-line surface roughness Ra of 1.0 ?m or higher, which includes a film substrate and a heat-sensitive adhesive layer formed on a backside surface of the film substrate, wherein the heat-sensitive adhesive layer is composed of a resin containing a crystalline polyester resin as a main component. The adhesive sheet of the present invention is excellent in adhesive property when the adhesive sheet is attached to the article made of a plasticized vinyl chloride resin. The adhesive strength of the adhesive sheet of the present invention is not decreased even after an autoclave treatment or storage at a low temperature.
