PROBLEM TO BE SOLVED: To provide a laminate such as a card or the like generating no warpage at the time of production or after keeping at high temp. SOLUTION: A laminate is produced by laminating at least a first substrate, an adhesive layer and a second substrate. In this case, the first and second substrates are different in the coefficient of thermal expansion and the 100% elongation load of the adhesive is set to 1-100 g/mm2. Warpage is hard to generate in a card produced from this laminate and, even if heat is applied to the card under a severe condition such that the card is kep in a dashboard of a car after formed, new warpage is not generated in the card. |
