A space truss is obtained that reduces the number of members forming longitudinal and transverse chord members or diagonal members and simplifies assembling operation or the like. Longitudinal and transverse chord members (2a, 2b; 3a, 3b) in an upper and lower lattices (2, 3) are formed by lattice-wise disposing long-sized bar members (8) having a length twice the intersection distance and connecting the connecting sections (8a, 8a) at the ends of long-sized bar members (8, 8) crossing a central connecting section (8b) to the latter, while diagonal members (4a, 4b) interconnecting the intersections (5, 6) of the chord members in the two lattices (2, 3) are formed by lattice-wise disposing V-shaped bent bar members (10) and connecting the connecting sections (10a, 10a) at the ends of the bent bar members (10, 10) crossing the connecting section (10b) in the middle of each bent bar member (10) to the connecting section (10b).
