Abstract
A composite fiber contains a component A as a core component and a component B at least partially covering the component A. The component A contains a vibration damping elastomer having a peak top intensity of tan δ of 0.5 or more. The component B contains a thermoplastic elastomer having a peak top intensity of tan δ of less than 0.5. The component B covers 70% or more of the cross-sectional perimeter of the component A in the fiber cross-section.
