PROBLEM TO BE SOLVED: To provide the joining structure of an inexpensive floor and wall which is easy in manufacturing and excellent in performance by stretching a floor plate material and a reverse plate material upward and downward of a floor frame, and erecting the wall on a floor panel integrated by filling a part therebetween with a foam heat insulation material. SOLUTION: A floor plate material 52 comprising a particle board and a reverse floor plate 53 comprising the particle board are stretched upward and downward of a floor frame 51. A foam urethane resin is foamed and filled without any gap into the inside of the floor frame 51 to be adhered. Next, after a screw nail is driven into a floor plate material 52 and a floor joist from the lower frame material of a wall 4 to be fixed, an inner wall material is nailed and fixed to erect and join a floor panel 5 and a wall 4. Thereby since the floor frame 51, the floor plate material 52, the reverse plate material 53 and a foam heat insulation material 54 are integrated, the strength of the floor panel 5 is large, the load of the upward erected and joined wall 4, fallen snow load on the floor panel 5 and the loading load of a room can be received by the whole floor panel 5, and they can be born sufficiently.
