PROBLEM TO BE SOLVED: To provide a temperature-responsive sheet having an adhesive force higher than an initial adhesive force by an exposure to high temperature, and capable of avoiding excessive increase of the adhesive force at a normal temperature, even with a further exposure to high temperature for an extended period thereafter.SOLUTION: In the temperature-responsive sheet, a peel adhesive force at temperature 25°C is 0.1 N/10 mm or less, a peel adhesive force at any temperature within a temperature range of 120-200°C is 0.1 N/10 mm or more. After the temperature-responsive sheet is adhered on a polyethylene naphthalate film and heated at 150°C for two hours, and subjected to standing at 25°C for three hours, a peel adhesive force to the polyethylene naphthalate film is 0.5 N/10 mm or less. |
