A splint for orthopedics for supporting the affected part of a patient suffering from a fracture or a sprain. A splint includes a support having 500˜1500 g/m2 of polyester non-woven fabric coated with a water-curable resin, an aluminum casing having a combination of polyethylene, aluminum and nylon (or polyester) in a pouch form to completely prevent the permeation of water so as to prevent the affected part from festering due to water, and a skin-protecting layer having polypropylene non-woven fabric and an outer surface layer having 200˜400 g/m2 of polyester, polypropylene or nylon, which are sequentially formed on the support. Unlike conventional splints for orthopedics which include a skin contact layer, a surface layer, and a support therebetween, the splint of the invention has a structure in which the support is directly packed with an aluminum casing, and an outer surface layer and a skin-protecting layer are provided thereon.
