PROBLEM TO BE SOLVED: To provide an elastic support and an elastic support apparatus using it, reducing distortion in the peripheral edge part of an elastic layer. SOLUTION: In this elastic support, the elastic layer 4 is integrally fixed between an upper steel plate 2 and a lower steel plate 3 spaced from each other and opposite to each other. Flat surfaces 8, 9 are provided rather closer to the central part in the radial direction in the opposite surfaces of the upper steel plate 2 and the lower steel plate 3, the upper steel plate 2 and the lower steel plate 3 are respectively provided with annular grooves 10, 11 connected to the respective flat surfaces 8, 9 and separate the opposite surfaces of the upper steel plate 2 and the lower steel plate 3 from each other, and a stress relaxing layer is formed by the thick elastic layer 4 between the bottoms 12, 13 of the opposite annular grooves 10, 11. In the elastic support, the widths of the flat surfaces 8, 9 are set larger than the widths of the annular grooves 10, 11 in the radial direction. The bottoms of the opposite annular grooves 10, 11 are formed as inclined surface 17, 18 gradually separating rather closer to the radial outside, and the thick elastic layer 4 between the bottoms 12, 13 of the respective annular grooves 10, 11 is gradually increased in thickness as it radially goes toward the outside.
