An object of the present invention is to provide: a rubber-fiber composite obtained by coating a core-sheath fiber with a rubber, in which adhesion between the rubber and the fiber is improved and which is thereby allowed to exhibit an improved durability as compared to conventional rubber-fiber composites when used as a reinforcing material; a rubber-resin composite; and a pneumatic tire using the same. The rubber-fiber composite is obtained by coating a reinforcing material with a rubber, which reinforcing material is composed of a core-sheath type composite fiber whose core portion is constituted by a high-melting-point resin having a melting point of 150°C or higher and sheath portion is constituted by an olefin-based polymer having a melting point lower than that of the high-melting point resin.
