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