Abstract:
An object of the present invention is to provide an adhesive tape having flexibility even at a low temperature, having excellent adhesive force at low temperature and after a certain period, and having excellent holding force after a certain period, and suppressing adhesive residue at peeling off even after being left for a certain period.
According to the present invention, provided is an adhesive tape comprising a substrate and an adhesive layer, wherein the adhesive layer is formed directly on the substrate or with another layer therebetween, the substrate contains a polyvinyl chloride resin, a plasticizer, and a zinc compound, a content of the plasticizer in the substrate is 30 to 50 mass % with respect to the total mass of the substrate, a content of a zinc atom in the substrate is 0.01 to 0.15 mass % with respect to the total mass of the substrate, and the adhesive layer contains an adhesive component and a vulcanizing agent.
