To provide a joint structure which is improved in its fatigue strength and both a joint body and a structural body which have the joint structures.SOLUTION: A joint structure comprises a first double skin construction member and a second double skin construction member bonded to the first double skin construction member. The first double skin construction member has a first projection part which projects more toward the second double skin construction member than a first outer rib, the second double skin construction member has a second projection part which projects more toward the first double skin construction member than a second outer rib and is piled on the first projection part from an inside in a plate width direction and the second projection part is thinner than the first projection part.SELECTED DRAWING: Figure 2
