PROBLEM TO BE SOLVED: To provide a jig which is fitted to an intersection part to hold a rod-like body for lattice frame assembly and its jig set when reinforcing bars as frames an: assembled in a lattice inside a concrete foundation ground at a construction site, wherein the work to fit the reinforcing bars to their intersection parts and assemble them in a lattice is considerably easy compared with the conventional practice, the working time is remarkably shortened, and the fixed intersection part is prevented from being loosened and generating any positional deviation even when the concrete is poured for placement. SOLUTION: A holding jig 7 holds a rod-like body for assembling a lattice frame of reinforcing bars in a concrete foundation ground. A first holding part to hold the rod-like body for assembling the lattice frame in one direction, and a second holding part to hold the rod-like body for assembling the lattice frame arranged in the direction orthogonal to the rod-like body for assembling the lattice frame held by the first holding part are provided on an upper part of a jig body 1.
