PROBLEM TO BE SOLVED: To provide an adhesive material which can be peeled easily, the adhesive material having adhesiveness at high temperature and having non-adhesiveness at low temperature.SOLUTION: The present invention employs an adhesive material which can be peeled easily, the adhesive material having a melting point equal to or more than 40°C and a glass transition temperature in a range of 20°C to a temperature higher than the melting point by 20°C. As an intermediate layer of the adhesive material which can be peeled easily and a support medium, an amorphous polymer is used, thereby, the adhesive material which can be peeled easily, which has adhesiveness at high temperature and has non-adhesiveness at low temperature, different from conventional one, is developed. |
