PROBLEM TO BE SOLVED: To develop a column beam joining structure in a column integrated column base fixing foundation structure excellent in overall performance for the technological purpose. SOLUTION: In a column material for cross-sectionally arranging a disphragm 11 in a lower part of a column 10 and arranging a baseplate 12 in a lower end part of the column 10, the diaphragm 11 and the baseplate 12 have a widely overhanging shape in a plan view in the direction for connecting an underground beam 2, and are characterized by arranging a web 13 between the diaphragm 11 and the baseplate 12 in this wide part, and in a column base unit 1 including the column material, since the wide part projecting from the column material is constituted as a connecting part with the underground beam 2, the underground beam 2 can be joined even to either place of this wide part.
