PROBLEM TO BE SOLVED: To enable operation of a bearing bush (1) formed in a hollow cylindrical shape mostly without inspection, to improve such that an extremely long using period can be provided and to enable the bush to be manufactured very simply at a low cost. SOLUTION: A slide bearing bushing comprises a first hollow cylindrical part (2) formed of a first material; and a second hollow cylindrical part (3) formed of a second material. The second hollow cylindrical part (3) is coaxially surrounded with the first hollow cylindrical part (2). The one of the first and second materials is a slide bearing material, and the other is a high tension material. A number of holes (4) having a central axis (5) vertical to a central axis (6) of a hollow cylinder to form both first and second hollow cylindrical parts (2, 3) are formed in a state to perforate through the first hollow cylindrical part (2) and the second cylindrical part (3).
