PROBLEM TO BE SOLVED: To constitute a floor panel having a supporting section on the lower floor side by a wall panel, a beam or the like in a size in an extent that there is the supporting section in sections excepting both end sections by a structure in which workability in the case of a transport and in the case of the execution of works is improved and the finishing working of the end faces of a peripheral section can be omitted partially. SOLUTION: The floor panel 10 having face materials 14 and 15 on the top faces of frame core materials 11, 12 and 13 is constituted by the structure having a section to be supported 16 to the supporting section 3 on the lower floor side in an intermediate section in the longitudinal direction. The section to be supported is configured by an opening space between a pair of lateral core materials 21 and 22 juxtaposed at a slight opening, and inserting sections 20 in which connecting bolts 30 connecting the lower-floor side supporting section 3 and the wall panel 4 on the upper floor side are inserted are formed previously to the section to be supported. The face materials constituting the floor panel are composed of the two face materials divided at places corresponding to the inserting sections, and edges are formed oppositely at a regular interval so that an opening section communicated with the opening space of the inserting sections is formed in these face materials.
