To provide a three-dimensional fiber conjugate that is readily produced even in the case of thickness and a complicated shape having difficulty in suturing using a sewing machine with yarn.

The three-dimensional fiber conjugate 11 is constituted of two three-dimensional woven fabrics F connected by rods 12. Each three-dimensional woven fabric F comprises a laminated yarn group 15 in which a plurality of x yarn layers 13 and a plurality of y yarn layers 14 of yarns arranged mutually parallel as yarn layers are laminated and formed to form an in-plane biaxial orientation and yarns z in the thickness direction arranged perpendicularly to the x yarn layers 13 and the y yarn layers 14 of the laminated yarn group 15 and has constitution that yarns are arranged in the three axial directions (X, Y and Z directions). The three-dimensional woven fabric F is formed in a planar quadrilateral plate in about 15 mm thickness. The rods 12 have acute angle tips.
