PURPOSE: A non-acrylic acid type adhesive composition and an adhesive film including the same with low resistance rate change are provided to enhance adhesive force with ITO surface. CONSTITUTION: A non-acrylic acid type adhesive composition satisfies chemical formula 1 and 2. The chemical formula 1 is as follows: resistance change rate(%) for ITO surface <= 15. The chemical formula 2: release strength ≥ 1000 g/in. The non-acrylic acid type adhesive composition includes the weight-average molecular weight of 500-10,000. The content of the additive is 0.01-5 weight% based on the total weight of the composition. The adhesive film for touch panels includes an adhesive composition or a cured product. The thickness of the adhesive film is 10-200 microns.
