The invention discloses a ballastless track slab. An included angle between each of an end face and a side face of a slab body of the ballastless track slab and a lower surface in the slab body is an acute angle, the projection of an upper surface which is downward in production on the lower surface is in a lower surface region, and the slab body of the track slab is provided with a jacking and demolding structure convenient for lifting the slab body from the bottom to top in a mold cavity so as to be demolded. The ballastless track slab disclosed by the invention has the characteristics that repeated mold assembly and mold removal are not needed in each manufacturing process of the track slab, and only an installed and adjusted mold is repeatedly used for producing the track slab, thereby improving the working efficiency and also ensuring coincidence indicator requirements, such as high accuracy and smoothness, of the track slab; moreover, the demolding method of the ballastless track slab reduces the requir
