A floor panel including structure for releasably connecting at least two panels. A tongue is formed extending in the longitudinal direction of the side edge and corresponding recess is formed opposite it. The recess comprises a top lip and a bottom lip, and the bottom lip forms a shoulder with a front shoulder side. The shoulder blocks the panels in the transverse direction. An undercut is adjoined by a recess, with a bearing region which corresponds to the shoulder, and a wall, which, with the front shoulder side in the installed state, is located opposite the latter. Form-fitting elements are formed on the wall and the front shoulder side that, in the installed state, engage one inside the other and bring about locking in the vertical direction. An underside of the tongue and a top side of the bottom lip runs parallel to the top side.
