PROBLEM TO BE SOLVED: To provide a laminated support having a damping performance equal to or higher than a laminated support with a metal plug embedded and requiring less cost for disposal etc. SOLUTION: The laminated support 10 is formed by alternately laminating a laminate 3 having an annular section formed by laying one over another rubber layers 1 and rigid plates 2 around a columnar plug 4. The rubber layers 1 consist of a rubber compound having an equivalent damping constant of 0.2 or higher when 100% strain at 0.3 Hz is input, and the plug 4 is composed of a plastic flow material consisting of an elastic perfectly plastic body and a hard filling material filled in the plastic flow material is filled.
