(Problem to be solved by the invention) In the case where the shape is devised using only the fiber reinforced composite material 10 (Fig. 7), the load is withstood only by the resin between the members, so the parts where the peeling force is applied are The problem was that it easily peeled off. Further, in the case of inserting a metal or a hardened fiber-reinforced composite material into the corner (FIG. 10), only an adhesive was used instead of the resin, but the same drawbacks as those described above existed. Furthermore, the methods of sewing with thread (Figure 8) and connecting with arrowhead-shaped metal fittings (Figure 9) not only require special equipment, but also have drawbacks such as being difficult to apply to actual structures.

(Means for solving the problem) Therefore, the present invention provides a filler made of fiber reinforced composite material at the boundary of a joint made by laminating members made of fiber reinforced composite material, and An adhesive having a lattice-like or mesh-like base material sprinkled with whiskers such as silicon carbide, or a fiber-reinforced composite material impregnated with resin is inserted around or inside, and molded and hardened at the same time as the above-mentioned member and filler. This is done in such a way that it is used as a means to solve problems.
