The present invention is to produce a shaped filler to be filled in a gap continuously and efficiently in producing the beam member made of the reinforcing fiber base material, even in the case where a cross-sectional surface of the gap having a wedge shape formed at a branching point of a reinforcing fiber base materials changes in a longitudinal direction of the beam member, at a cross-sectional surface orthogonal to the longitudinal direction of the beam member. For the objective, a process for producing a beam member formed by a reinforcing fiber base material which has a web portion and at least a pair of flange portions extending to both sides via at least a branching point from the web portion, at a cross-sectional surface orthogonal to a longitudinal direction of the beam member, and by a shaped filler which fills a gap having a wedge shape formed at the branching point, is provided, wherein the shaped filler is produced by at least the following production processes (A) to (C): (A) a filler supply process for supplying a filler member configured by reinforcing fibers; (B) a preshaping process for providing a preshaped filler having at least a wedge projection portion, by pressurizing the filler member by a preshaping mold; and (C) a filler deforming process for providing a shaped filler by deforming the preshaped filler, by filling the preshaped filler into the gap and by pressurizing the preshaped filler such that a tip of the wedge projection portion is directed to a tip of the gap having a wedge shape.
