According to the foundation block connection structure, the footing portions 7, 7a of the local foundation blocks 2 to 5 and the extended foundation blocks 6 are set to have the same height, and the foundation erect wall portions 9, 9a of the same are also set to have the same height. Further each of the footing portions 7, 7a has a footing recess 25 and a footing projection 23 formed in and on connection edges thereof, respectively, for tongue and groove engagement, and the footing recess 25 and the footing projection 23 are engaged with each other to connect each of the local foundation blocks 2 to 5 and the extended foundation block 6 together, which leads to construction of the foundation 1.
