To obtain a hollow-shaped continuous reinforcing material suitable for an anchor bolt embedded in an installation hole provided in a bedrock or a stratum by impregnating a specific continuous braided tube with a resin.

This hollow-shaped continuous reinforcing material is obtained by using at least one fiber selected from the group of a carbon fiber, a glass fiber, an aramid fiber, a ceramic fiber, a steel fiber, a polyester fiber, a high- strength polyolefin fiber, a polyamide fiber and a polyvinyl alcohol fiber, arranging 10-90wt.% longitudinal yarn 1 around an axial line (a) and fibers 2 helically present on the outer peripheral surface of a braided tube, knitting the continuous braided tube, impregnating the resultant braided tube with at least one resin selected from the group of an epoxy resin, an unsaturated polyester resin, a vinyl ester resin and a phenol resin and forming the hollow-shaped continuous reinforcing material at 40-90wt.% ratio of the braided tube.
