A floor element for forming building floors, which is designed in the form of a wood/reinforced concrete composite part, includes at least two wood beams (1-4) extending parallel to each other in a longitudinal direction of the floor element and a reinforced concrete body (5), which has a plate-shaped section (6) resting on the wood beams (1-4). Furthermore, the reinforced concrete body (5) has first and second sections designed in the form of edge beams (7, 8), which extend at an angle to the wood beams (1-4) and lie against the opposite end faces (9, 10) of the wood beams (1-4).
