A cell type steel composite structure is provided to plan a retaining wall structure for securing resistance to earth pressure more effectively by forming a cell type steel structure having flexibility and stiffness, to increase drainage efficiency and to enlarge resistance to load. The cell type steel composite structure includes a primary steel plate(10) composed of a strip type steel plate folded in many repeated shapes, a secondary steel plate(20) formed in the same shape and material to the primary steel plate, and fixing bolts(30) connecting the primary steel plate and the secondary steel plate in a line. The primary and secondary steel plates are provided with many bolt holes(32) to fasten the fixing bolts and coupled with each other to form many cells(40) between the primary and secondary steel plate to fill up with fillers(50), and many minute holes(70) are perforated on the surface of the primary and secondary steel plates except the ridges and grooves where bolt holes are formed at regular intervals.
