An object of the invention is to provide a method for producing a structural member and the structural member, in which the structural member including a composite material can efficiently be produced such that strength of the structural member is sufficiently ensured while generation of a wrinkle in a composite material sheet is prevented even in a three-dimensionally curved portion of the structural member. A narrow prepreg sheet 20N is bonded along a ridge C, and wide prepreg sheet 20W is bonded to other portions, whereby the wide prepreg sheet 20W having no cut line is bonded to both side portions of the ridge C. In a portion in which a spar 10 is curved, the narrow prepreg sheet 20N is bonded in an axial direction of the spar 10 while divided into plural pieces, and a length of the narrow prepreg sheet 20N is adjusted according to a radius of curvature of the curved portion in the axial direction of the spar 10, whereby various radii of curvature are easily dealt with.
