Abstract: In a conductive film for touch panel, a first electrode pattern is formed on the main surface at one side of an insulating layer, a second electrode pattern is formed on the main surface at the other side of the insulating layer, an adhesive insulating layer is disposed on at least one of the first electrode pattern and the second electrode pattern, an acid value of an adhesive insulating material contained in the adhesive insulating layer is equal to or greater than 10 mg KOH/g and equal to or less than 100 mg KOH/g, either or both of the first electrode pattern and the second electrode pattern contain silver, and a rate of change in mutual capacitance (%) between the first electrode pattern and the second electrode pattern before and after performing an environmental test is 0% to 100%.
