Summary:To provide an electroacoustic transducer capable of achieving high performance.SOLUTION: An electroacoustic transducer 100 that has a gap 101 and gap maintenance material 150 disposed in the gap 101. The gap maintenance material 150 contains a base liquid 151 that contains polyhydric alcohol and is held in the gap 101 due to its own surface tension, and a granular material 152 dispersed in the base liquid 151 and has rubber elasticity.SELECTED DRAWING: Figure 1 【課題】高性能化を図ることができる電気音響変換器の提供。【解決手段】間隙部１０１を有し、間隙部１０１に間隙維持材１５０を備える電気音響変換器１００であって、間隙維持材１５０は、多価アルコールを含み自身の表面張力により間隙部１０１に保持される基礎液体１５１と、基礎液体１５１中に分散保持され、ゴム弾性を有する粒状体１５２とを備える電気音響変換器１００。【選択図】図１
