To provide a core metal for an elastic crawler which is highly durable with respect torsion acting on the core metal during use, and to provide an elastic crawler using the core metal.SOLUTION: A core metal 30 for an elastic crawler comprises: a long core metal base body 31; a pair of projections 32L, 32R projecting from a longitudinal middle part of the core metal base body 31; and a pair of rail portions 34L, 34R projecting from the core metal base body 31 on outside of the pair of projections 32L, 32R and having a roller support surface 35 supporting a roller 56 rolling on an inner peripheral surface of the elastic crawler 10. A top surface 37 projecting from the core metal base body 31 and continuously formed from the roller support surface 35 has a pair of rail extensions 36L, 36R extending from the rail portions 34L, 34R toward the longitudinal middle of the core metal base body 31.SELECTED DRAWING: Figure 4
