PROBLEM TO BE SOLVED: To provide a connection structure of a space truss that facilitates connecting truss members whose each node is formed by a plate material when constructing a space truss frame having an arbitrary curved surface. SOLUTION: A lower chord node joint hardware 8 is disposed at a node of a lower chord 2 and a lattice member 3. The lower chord node joint hardware 8 is composed of a plurality of core plates 8a arranged in an approximately cross shape in a plan view so as to make their axial direction coincide with the axial direction of an upper chord, a plurality of gusset plates 8b each arranged at a recessed corner c consisting of adjacent two core plates 8a, 8a so as to make their axial direction coincide with the axial direction of the lower chord 2, and a plurality of gusset plates 8c each arranged at the recessed corner c so as to make their axial direction coincide with the axial direction of the lattice member 3, and a rib plate 8d is attached between the gusset plate 8b and the gusset plate 8c.
