PROBLEM TO BE SOLVED: To provide a roof header capable of more effectively reducing in-cabin noise and vibration without causing increase of weight and cost. SOLUTION: The roof header 1 is a roof header 1 supporting a panel constituting a roof of the vehicle and extending in a vehicle width direction. A portion 1a constituting an antinode of primary resonance in the roof header is constituted by anisotropic fiber member, and a main extension direction of the fiber constituting the anisotropic fiber member is made to a vehicle width direction.
