Since it is embedded from the inside of the part to the bottom wall part through the forming plate of the hollow box-shaped part, it is possible to improve the strength while maintaining the weight reduction. Moreover, it is built on site after manufacturing at the factory. During transportation or storage, foreign matter does not adhere to the inside and quality is maintained, and even at the time of concrete pouring work, the work of sealing the bottom end of the pillar is more difficult than the pillar member with vertical penetration structure. It is not necessary to do the above, and the work to fit the upper end becomes easy.
（３）上記軽量化により工場から構築現場への運搬が容
易になり、かつ現場での揚重機の作業範囲を拡大でき、
現場での作業能率が向上する。(3) Due to the above weight reduction, transportation from the factory to the construction site is easy, and the working range of the lifting machine on the site can be expanded.
Work efficiency in the field is improved.
（４）またそれらにより労務の省力化、工期短縮、高品
質化及び現場管理作業の合理化を達成できる。(4) Moreover, labor saving, shortening of construction period, high quality and rationalization of site management work can be achieved by them.

と後打ちコンクリートとの結合力が向上する。(5) In the pillar member manufacturing method, when forming a hollow pillar member made of precast concrete, a lath member having a large number of medium through holes is stretched inside the pillar rebar assembly and used as an inner formwork. Therefore, the column main bar can be easily formed in the embedded state, and the front wall surface of the space S1 can be formed into an uneven surface, thereby improving the bonding force between the precast concrete portion and the post-cast concrete.
