The invention provides a structure of a pile head joint portion and a pile had fitting tubular body which can absorb an execution error for constructing a pile leading to a problem in the case of precasting a board for supporting an upper structure in order to intend to shorten a process, and can improve a strength of the pile head joint portion. A precast board (5)is manufactured by embedding a pile head fitting tubular body (2) which is constituted by a side plate (23) forming a pile head fitting tubular body (2) and a closing plate (22) closing open one end of a tube body, and forms an opening portion (26) in another end open so as to freely fit a pile head. The pile and the board are integrally formed by fitting the pile head portion to the pile head fitting tubular body (2) after constructing the pile, and charging an injection material (4) into the pile head fitting tubular body (2).
