Adhesive tape for electrochemical devices

Provided is an adhesive tape for electrochemical devices, which can be used in electrochemical devices for the purpose of preventing an active material from being falling out or the like, and which can be prevented from being adhered onto a cutting blade after the adhesive tape is cut. The adhesive tape for electrochemical devices according to the present invention is an adhesive tape for use in the production of electrochemical devices, and is characterized by comprising a base and an adhesive agent layer formed on one surface of the base, wherein the adhesive agent layer contains an acrylic polymer as a base polymer, and is also characterized in that the adhesion strength upon peeling at an angle of 180DEG which is measured after compressing at a temperature of 40DEG C or higher and lower than 150DEG C (adhered onto a SUS304BA plate, peeling temperature: 25DEG C, peeling speed: 300 mm/min) is two-fold or more higher than the adhesion strength upon peeling at an angle of 180DEG which is measured after compressing at 25DEG C (adhered onto a SUS304BA plate, peeling temperature: 25 C, peeling speed: 300 mm/min).
