Abstract: Provided are a pressure-sensitive adhesive tape in which anchoring failure is suppressed and a method of producing the pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape includes a base material including an olefin-based resin, a first pressure-sensitive adhesive layer including an olefin-based resin, and a second pressure-sensitive adhesive layer including a styrene-based elastomer in the stated order. The method of producing a pressure-sensitive adhesive tape is a method of producing a pressure-sensitive adhesive tape including a base material including an olefin-based resin, a first pressure-sensitive adhesive layer including an olefin-based resin, and a second pressure-sensitive adhesive layer including a styrene-based elastomer in the stated order, the method including: applying a pressure-sensitive adhesive composition for forming the first pressure-sensitive adhesive layer to the base material by hot-melt coating; and applying a pressure-sensitive adhesive composition for forming the second pressure-sensitive adhesive layer to the first pressure-sensitive adhesive layer by the hot-melt coating.
