PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive double coated tape used for adhering component articles, such as plastic and foamed component articles, to molded articles, such as metal and plastic articles, preventing the pressure- sensitive adhesive mass from being left on the molded article side, preventing itself from breaking or fracturing between substrate layers, and therefore having good release properties, when the component articles are released from the molded articles with the aim of recycling the molded articles. SOLUTION: This pressure-sensitive adhesive double coated tape comprises a nonwoven fabric, as a substrate, which has a thickness of 30-80μm and comprises 100% of Manila hemp, a rerelease type pressure-sensitive adhesive mass layer which contains an acrylic ester copolymer having an weight-average molecular weight of 600,000 to 1,000,000 as a main component and is applied to a single side of the substrate, and a pressure-sensitive adhesive layer which contains an acrylic ester copolymer having an weight-average molecular weight of <=500,000 as a main component and is applied to another side of the substrate, wherein each of the both adhesive layers has a thickness of 50-90μm.
