Provided is a belt material having excellent high-temperature mechanical properties. The belt material has a cross-linked fluorine rubber layer obtained by cross-linking a fluorine rubber composition that contains fluorine rubber (A) and carbon black (B), the cross-linked fluorine rubber layer exhibiting a loss modulus (E") of 400-6000kPa, inclusive, when subjected to a dynamic viscoelasticity test (Measurement temperature: 160°C, tensile strain: 1%, initial loading: 157cN, frequency: 10Hz). La présente invention concerne un matériau de ceinture ayant d'excellentes propriétés mécaniques à haute température. Le matériau de ceinture a une couche de caoutchouc fluoré réticulé obtenue par réticulation d'une composition de caoutchouc fluoré qui contient du caoutchouc fluoré (A) et du noir de carbone (B), la couche de caoutchouc fluoré réticulé présentant un module de pertes (E") de 400 à 6000 kPa, inclus, lorsqu'elle est soumise à un essai de viscoélasticité dynamique (température de mesure : 160 °C, contrainte de traction : 1 %, charge initiale : 157 cN, fréquence : 10 Hz).
