The present invention provides an adhesive tape for electrochemical devices that has excellent adhesive force, does not adversely affect electrochemical devices, protects electrodes, prevents peeling of active materials, and is capable of rolling laminates such as electrode plates and separators. Fix the tail of the roll when winding it into the battery case. The adhesive tape for electrochemical devices of the present invention is characterized in that it has an adhesive layer formed of an acrylic adhesive on at least one side of a plastic base material, and the acrylic adhesive contains at least ( An acrylic polymer obtained by polymerizing monomer components of alkyl methacrylate and a hydroxyl group-containing monomer, having an acid value of 1.0 or less and a glass transition temperature (Tg) of -40°C or higher. |
