PROBLEM TO BE SOLVED: To provide an auxiliary member for joining, which can be appropriately arranged with respect to a stress direction, which is not displaced even during construction and which is not rotated by corotation in bolting, and a joining structure. SOLUTION: In an inequilateral octagon-shaped auxiliary member 61 for joining, a distance between a pair of sides 61d and 61d orthogonal to a protrusion 61b is shorter than a distance between a pair of sides 61c and 61c parallel to the protrusion 61b. When high-strength bolts 64 are linearly arranged, the sides 61c and 61c abut on each other. When the high-strength bolts 64 are arranged in a zigzag manner, sides 61e and 61e or 61f and 61f, which cross each other at an angle of approximate 45°with the protrusion 61b, abut on each other. The side 61d is parallel to the longitudinal direction of a base material 62, and one side is closest to the outside. Since the auxiliary member 61 is formed in an inequilateral octagon shape, it is put inward from the vicinity of an outer edge of a splice plate 63, and becomes hard to rust.
