A method for manufacturing a solid structural material using a three-dimensional five-axial woven fabric W. In weaving a three-dimensional five-axial woven fabric W using a three-dimensional weaving machine, divisibly woven sections S1 are formed in portions of a manufactured three-dimensional five-axial woven fabric by alternately driving upper and lower insertion members 2, 3 for inserting a vertical yarn Z from above and below, respectively, in such a manner that each of the insertion members and a weft insertion rapier are driven with different timings.
