The wave shaped reinforced part (30) is located on at least one of the upper portion, midpoint or lower portion. The golf club shafts (25B) of the present invention can be made by applying a base section (2B) of a prepreg sheet (2A) or assembly having a plurality of finger like elements (2) to a portion of a base shaft (5), wrapping the finger like elements (2) around the base shaft (5) to provide a wave shaped reinforced part (30) having a plurality of reinforcement pieces, and curing the shaft having the wave shaped reinforced part (30) thereon to produce a golf club shaft (25B) having a wave shaped reinforced part (30).
