(57) [Abstract] [Problem] No toxic gas is generated by combustion during incineration, and excellent heat deformation resistance and flame retardancy (more excellent elongation) And a pressure-sensitive adhesive tape substrate used for the pressure-sensitive adhesive tape. SOLUTION: The substrate contains an olefin-based polymer and an inorganic flame retardant and is substantially free of a halogen atom. An adhesive layer is formed on at least one surface of the substrate, and the substrate is heated at 100 ° C. An adhesive tape having a deformation rate of 65% or less and a breaking elongation at a tensile speed of 300 mm / min of 150% or more. |
