PROBLEM TO BE SOLVED: To provide a connection structure between a column and a beam, which can prevent cracking of concrete on a basement even if high-strength concrete is used, and is good in cost efficiency, and to provide a method of constructing the connection structure. SOLUTION: In the connection structure 1 between the column and the beam, a cross sectional area of a column-beam connection portion 2 on a lower side of a first-floor column of a steel reinforced concrete structure is made larger than the cross sectional area of the first-floor column 3 and the cross sectional area of a basement column 4.
