PROBLEM TO BE SOLVED: To provide a high rigidity lattice wall easy in manufacture, and capable of extremely enhancing rigidity of a joining part. SOLUTION: A vertical material 2 is composed of a long size material, and a horizontal material 3 is divided into a plurality of beads-like short size materials 3a. The long size material 2 and the beads-like short size material 3a are alternately and repeatedly juxtaposed, and a core material 4 penetrates through these materials. A fastening material 5 provided in both end parts of the core material 4 is fastened in the approaching direction by a nut 7. The repeatedly juxtaposed long size material 2 and beads-like short size material 3a are put in a compressed state from both sides. COPYRIGHT: (C)2006,JPO&NCIPI
