PROBLEM TO BE SOLVED: To provide a foundation structure for a structure, which has good workability by virtue of a simple constitution, and which brings about an improvement in productivity and a reduction in cost by securing the degree of freedom of equipment piping and a double pit equipped with a manhole enabling the entrance/exit of an operator in maintenance. SOLUTION: This foundation structure 4 of the structure 1 comprises: a mat foundation 5 which directly transfers a load of an upper structure 3 to ground; and a connection member 6 which is arranged in a position wherein a column base part of a column 2 constituting the upper structure 3 is joined by a top surface of the mat foundation 5, and which is constructed so as to be integrated with the mat foundation 5. Though the connection member 6 makes the column base part of the column 2 and the mat foundation 5 joined together, stress of the column 2, which is associated with the occurrence of an earthquake etc., is smoothly transferred to the mat foundation 5. Thus, a footing beam is made unnecessary, so that one open space, which is as large as the base area of the upper structure 3, can be formed between the mat foundation 5 and a floor slab 3a, and the double pit 7 is formed in the open space.
