This invention is to provide structural member joints capable of easily reinforcing connecting portions of structural members and a structure using the structural member joints. Each structural member joint includes three tubular joint members into which end portions of the structural members 7 can be inserted and fixed. The three tubular joint members are connected to each other at their proximal end portions and disposed at right angles to each other. Since the distal end portions of the joint members 2 arranged at right angles to each other are connected by the reinforcing members 6, it is possible to use the reinforcing members 6 to easily reinforce the connecting portions of the structural members 7.
