Summary:To improve the performance of an electro-acoustic transducer while reducing the size.SOLUTION: An electro-acoustic transducer 100 including a low friction material 150 in a sliding part. The low friction material 150 contains: an inflated body 105 in which a second polymer chain 152 having a siloxane bond as side chain branches multiple times from the first polymer chain 151; and a swelling liquid 153 that has silicone infiltrating between the second polymer chains 152.SELECTED DRAWING: Figure 2 【課題】電気音響変換器の高性能化、小型化を図る。【解決手段】摺動部に低摩擦材料１５０を備える電気音響変換器１００であって、低摩擦材料１５０は、第一高分子鎖１５１から側鎖としてシロキサン結合を有する第二高分子鎖１５２が複数分岐する被膨潤体１０５と、第二高分子鎖１５２の間に浸潤するシリコーンを有する膨潤液１５３と、を備える電気音響変換器１００。【選択図】図２
