摘要： There is provided a truss element in which space truss diagonal members can be easily integrally formed by being drawn in a predetermined direction. This truss element is formed in a corrugated shape with mountain portions 1a and valley portions 2 in left and right directions alternately and cut portions 4a, each which is perpendicular to a ridge line 3 of the mountain portion 1 and leaves a bottom of the valley portion uncut, and cut portions 4b, each which is perpendicular to a bottom line 5 of the valley and leaves a peak of the mountain portion uncut, are formed alternately with spaces in a front and back directions.
