Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a urethane resin maintaining mechanical strength of the resin such as tensile break strength even in the temperature region of 100°C or higher.SOLUTION: This urethane resin (A) includes an ester (e) of 1,2,4-benzenetricarboxylic acid (c) and 2-10C aliphatic diol (d1) or dialkanolamine compound (d2), and polyisocyanate (i) as constitutional units; the temperature at which the storage elastic modulus (G') becomes 20,000 (dyn/cm) is 100°C or higher, and the storage elastic modulus [G'150](dyn/cm) at 150°C and the storage elastic modulus [G'180](dyn/cm) at 180°C satisfy the following formula (1): [G'150]/[G'180]≤12.
