PROBLEM TO BE SOLVED: To provide a vehicle skeleton member including a member formed of a composite material of a thermoplastic resin and a reinforced fiber which imparts a high bonding strength to a fastened site of the composite material, and has a sufficient strength as a vehicle structure.SOLUTION: A vehicle skeleton member includes a fastened surface fastened by vibration welding a plurality of members having a two-dimensionally random fiber-reinforced composite material containing a thermoplastic resin and a chopped fiber which is oriented in two-dimensionally random form, and includes an axis parallel to a front-rear direction of a vehicle and/or a right-left direction of the vehicle in the fastened surface. A ratio of the fastened surface is 50-100% of the area of the fastened surface.SELECTED DRAWING: Figure 3
