In the connection structure of tent poles, both ends of a connecting rod are inserted into opposing ends of a pair of tent poles to connect the tent poles and the connecting rod has an outer diameter corresponding to inner diameters of the tent poles. A widened tubular part is formed on at least one of ends of the tent poles and has a diameter larger than that of the end on which the widened tubular part is formed. An end of the connecting rod has an outer diameter corresponding to an inner diameter of the widened tubular part and is inserted and fixed into the widened tubular part. A magnitude of the moment of inertia of the connecting rod is 60% or more of the moment of inertia of the widened tubular part of the tent pole.
