PROBLEM TO BE SOLVED: To provide a rubber crawler capable of preventing a tear of a crawler body caused by an external damage from reaching a core, and suppressing the motion of the core when the dynamic stress is exerted from the outside. SOLUTION: The rubber crawler comprises a crawler body 6 consisting of endless strip shaped peroxide crosslinked rubber, cores 7 which are embedded inside the crawler body 6 with intervals in the circumferential direction with an unsaturated polyester resin film 8 formed on its circumferential surface, and a lug group consisting of a plurality of lugs 9 formed on an outer circumferential surface 6a of the crawler body 6. The unsaturated polyester resin film 8 of 1.2-5 mm thick is formed on the circumferential surface of the core 7. The unsaturated polyester resin to constitute the unsaturated polyester resin film 8 and the rubber to constitute the crawler body 6 are subjected to crosslinking adhesion to each other with peroxides, and the blend of the peroxides is set to be 0.2-1.6 phr.
