The invention provides a steel plate reinforcing sheet having light weight and thin layer, providing sufficient adhesion and reinforcing effect to a steel plate (4), and having excellent workability. In the steel plate reinforcing sheet comprising a restricting layer (1) and a resin layer (2), a curing composition is first prepared by mixing rubber components comprising diene-based rubber and rubber having a vinyl group in its side chain, with a cross-linking agent capable of reacting with these rubber components, and then by kneading the mixture. Thereafter, the curing composition thus prepared is rolled by molding, to form a resin layer (2). Then, the resin layer (2) thus formed is adhesively bonded to the restricting layer (1), to produce a steel plate reinforcing sheet. |
