Summary:This elastic surface wave device (1) comprises: a piezoelectric substrate (20) having main surfaces (20a, 20b); and an IDT electrode (40) disposed on the main surface (20a) among the main surfaces (20a, 20b), the main surface (20a) being the polarized positive-potential surface of the piezoelectric substrate (20). Ce dispositif à ondes de surface élastiques (1) comprend : un substrat piézoélectrique (20) ayant des surfaces principales (20a, 20b); et une électrode IDT (40) disposée sur la surface principale (20a) parmi les surfaces principales (20a, 20b), la surface principale (20a) étant la surface à potentiel positif polarisée du substrat piézoélectrique (20). 弾性表面波装置（１）は、主面（２０ａおよび２０ｂ）を有する圧電基板（２０）と、主面（２０ａおよび２０ｂ）のうちの主面（２０ａ）側に配置されたＩＤＴ電極（４０）と、を備え、主面（２０ａ）は圧電基板（２０）の分極正電位面である。
