The invention relates to an animal ear tag that comprises a spike (1) and two outer parts (2, 3), which come to rest on opposite sides of the animal's ear, wherein the spike (1) has a plurality of parts (5, 6, 7), made of a relatively hard material and arranged one behind the other in the longitudinal direction of the spike (1), and another part made of an elastically softer material and extending, in the longitudinal direction of the spike (1), along a plurality of the parts (5, 6, 7) made of a relatively hard material, connecting the same. The parts (5, 6, 7) that are made of a relatively hard material are stacked on one another. The part that is made of an elastically softer material is a sheath (8), which encases a plurality of the stacked parts (5, 6, 7) made of a relatively hard material, on the lateral surface of the stack that is formed by said parts.
