The utility model relates to a track slab for a ballastless track, and aims at enabling the track slab to form an integral combined track structure together with an adjusting layer and a bearing layer, wherein, the structure is further simplified, and the prefabrication production and the field construction are more convenient. The track slab (10) adopts a prestressed reinforcement concrete structure, the slab body of the track slab adopts a flat plate, the orthographic projection of a slab surface is in the shape of a rectangle, and a connecting element extending out of the bottom surface of the slab body is fixedly arranged in the track slab in an embedding manner.
