PROBLEM TO BE SOLVED: To provide a slit structure of an exterior wall capable of preventing concrete from deteriorating, damage or the like in the outdoor side end section of the bottom of the exterior wall and having cut-off efficiency and workability. SOLUTION: In the slit structure of the exterior wall forming a horizontal slit between a lower side of the exterior wall 10 and a beam 20, the bottom of the exterior wall includes an inside flat section 11 extended toward the outdoor side from the indoor side end section in the direction of the thickness and an outside flat section 13 positioned to the downward outdoor side end section rather than the inside flat section 11, and a slope section 12 for a slit height S to gradually become small from the upper surface of the beam in the inside flat section toward the outside flat section is formed between the inside flat section 11 and outside flat section 13. The lower end edge of the outside flat section 13 is approximately positioned at the upper side of the beam 20. On the upper side of the beam 20, a recess section 21 is notched and formed in a corner section of the outdoor side.
