Research Abstract	This study aimes to examine a durability evaluation method for wooden members reinforced by carbon fiber material. It is required to evaluate the durability of a carbon fiber reinforcement part from a viewpoint of maintenance management. Environmental conditions such as temperature and humidity around member of the wooden bridge were measured for four months to grasp conditions of the construction site. These are used as experimental conditions for a carbon reinforced wooden member, and natural exposure test and heat cycle test were carried out. Using these tested members, bending performance and adhesion characteristics were analyzed. Finally, a mechanism of deterioration was considered from the correlativity of the adhesion and the bend characteristic. As a result of the weather resistant test on the surface of the carbon fiber material of the lacquer painting, it was indicated that the deterioration characteristic on the surface was similar to wood.
