PROBLEM TO BE SOLVED: To provide a partition wall structure where a plurality of layer walls P1, P2 and P3, each formed of a plurality of boards p with nail-retaining forces and fire-resisting performance with the end faces of the boards p abutting one another, are laid one on top of another and fastened together using screws n as they are positioned in such a manner that the junction lines L1, L2 and L3 of the boards constituting each of the layers do not overlap one another. SOLUTION: A plurality of layer walls, each of which is formed of a plurality of boards p having nail-retaining forces and fire-resisting performance with their end faces abutting one another, are laid one on top of another and screwed together as they are positioned in such a manner that the junction lines of the boards constituting each layer do not overlap one another, thereby achieving the practical heat- and fire-resisting performance of the partition wall structure.
