PROBLEM TO BE SOLVED: To provide a coupling member which can effectively absorb energy of vibration in a joint part between a wooden member and a jointed member, a method of manufacturing the coupling member and a wooden member joint structure using the coupling member.SOLUTION: A metal coupling member 11 is embedded in and fixed to a wooden member 1, the coupling member and a joint metal fitting 12 fastened to a base 3 being a jointed member are coupled together, and thereby the wooden member and the jointed member are jointed. The coupling member includes a metal rod-like main body part 31 to be embedded in the wooden member and held, and a middle shaft part 32 which protrudes from one end surface of the main body part and is coupled to the jointed member to be jointed to the wooden member or the joint metal fitting fastened to the jointed member. The middle shaft part permits the relative displacement in the axial direction with the side surface separated from the main body part from the portion protruding from the end surface of the main body part to a prescribed depth in the axial direction of the main body part and is integrally continuous with the main body part at the deepest part. 【課題】木部材と被接合部材との接合部分で振動のエネルギーを有効に吸収することを可能とする結合部材、この結合部材の製造方法及びこの結合部材を用いた木部材接合構造を提供する【解決手段】 木部材１に金属の結合部材１１を埋め込んで固定し、該結合部材と被接合部材である基礎３に固着された接合金具１２とを結合することによって木部材と被接合部材とを接合する。結合部材は、木部材中に埋め込んで保持される金属の棒状となった本体部３１と、本体部の一方の端面より突き出し、木部材と接合される被接合部材又は被接合部材に固着された接合金具に結合される中軸部３２とを有する。中軸部は、本体部の端面より突き出した部分から該本体部の軸線方向の所定の深さまで、側面が該本体部と分離して軸線方向の相対的な変位を許容するとともに、最深部では該本体部と一体に連続するものである。【選択図】図３
