PROBLEM TO BE SOLVED: To provide a connection structure of a steel member capable of facilitating connecting operation with less number of components, preventing a fitted part from being rattled, and increasing strength. SOLUTION: In this connection structure of the steel member, steel members of roughly rectangular shape having connection legs facing each other formed projectedly at their connection parts are connected to each other by fitting the connection legs to each other, the upper connection leg 20 of one steel member 1 is formed by forming an engagement projection 21 on the inside of its base end part, forming a recessed groove 23 overlappingly with the engagement face 22 of the engagement projection 21, and forming a sharp projected part 24 at its tip part. The lower connection leg 30 of the other steel member is positioned on the inside of the upper connection leg of one steel member, and formed by forming, at its tip part, an engagement projection and an outward locking claw 31 engaged with the recessed groove, and forming, at its base end part, a fitting groove 32 of approximately V-shape in cross section fitted to the projected part. To connect the steel members to each other, the projected part is fitted to the fitting groove, and the engagement projection is adhered to the recessed groove and the locking claw through an adhesive agent 50 filled in the recessed groove.
