Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a Joining method, in which the generation of the shear fracture of a woody material as a base material is prevented while separation generated on the interface of a grout material and the woody material is reduced and which can resist the extraction load of a joining member effectively when the woody material is joined through the joining member. SOLUTION: In the joining method of a woody material, the woody material 1 is divided into split pieces 10, recessed grooves are excavated to these split surfaces 10a while deformed steel pipes 5 having a shape engaged with the irregularities of the recessed grooves are disposed into the recessed grooves while the split pieces 10 are laminated. The insides of the deformed steel pipes 5 are filled with a filling solidifying agent and the agent is solidified, reinforcing bars 4 inserted into the deformed steel pipes 5 are fixed, and the woody material 1 is joined with other members through the reinforcing bars 4.
