Zusammenfassung:	To provide a sound absorber for a pneumatic tire, effectively suppressing noise and vibration generated in rotation rolling of the tire.SOLUTION: A sound absorber is attached to an inside surface of an inner liner of a rolling tire, and/or an outer peripheral surface of a wheel. The sound absorber comprises a nonwoven fabric having a basic raw material made of nanofiber using a synthetic resin, and having a fiber diameter of 10-1,000 nm, and is formed in a belt-like shape so as to extend over an inner surface of a tread part. A tire attached with the sound absorber is also provided.SELECTED DRAWING: None 【課題】タイヤの回転転動時に発生する騒音や振動を、効果的に抑制する空気入りタイヤ用の吸音材を提供する。【解決手段】転動タイヤのインナーライナーの内側面、及び／又は、ホイールの外周面に取着される吸音材であって、該吸音材は合成樹脂系を用い、繊維径が１０〜１０００ｎｍのナノファイバー製を基本素材とする不織布からなり、トレッド部の内面に亘るように帯状形状に構成されたことを特徴とする吸音材、及び該吸音材を取着したタイヤ。【選択図】なし
