A vibration damping shaped aluminum extrusion achieves the features of weight reduction and a high damping effect. The vibration damping shaped aluminum extrusion includes a pair of face plates which face each other and a plurality of ribs connecting the face plates, wherein a damping material is provided at least on the central part of the rib in an inner surface of a hollow part formed by the face plate and the rib. A positioning recess or a positioning protrusion may be formed so that a damping material is provided on the central part of the face plate in an inner surface of the hollow part.
