To provide a reinforcing material which is applicable to a surface of a complicated shape and is highly resistant against erosion.

An erosion-resistant material 10 has an elastomer 12 layer and a fiber-reinforced material 14 layer. The fiber-reinforced material 14 is substantially reinforced with a fiber and an uncured elastomer 12 is supported or reinforced with the fiber-reinforcing material 14. In manufacturing, this uncured elastomer 12 and the fiber-reinforced material 14 are thermally pressed at temperatures higher than the fluidization point of the elastomer 12 and lower than the curing point, i.e., curing temperature of the elastomer 12, and at a pressure high enough to cause the heated uncured elastomer to flow into the fiber-reinforced material.
