A fiber-reinforced composite material and a method for manufacturing the same. A first binder resin is applied to a first portion for forming a deformed part of a fiber base material, and a second binder resin is applied to a second portion excluding the first portion. The fiber base material is then heated so that the degree of melting of the first binder resin during shaping is less than the degree of melting of the second binder resin, and the second binder resin is softened. Shaping is then performed so that a deformed part is formed in the fiber base material, and a preform is obtained. A fiber-reinforced composite material is obtained using the preform as a molding precursor.
