【実用新案登録請求の範囲】[Scope of utility model registration request] 圧電基板と、その表面にもうけられるくし形電極とを有
する表面弾性波変換器において、表面弾性波励振に寄与
しないダミー電極にλ／８（λは波長）幅のスプリット
電極指を用い、表面弾性波励振に寄与する電極にλハ幅
の電極指を用いた事を特徴とする表面弾性波変換器。In a surface acoustic wave transducer that has a piezoelectric substrate and comb-shaped electrodes formed on its surface, split electrode fingers with a width of λ/8 (λ is the wavelength) are used as dummy electrodes that do not contribute to surface acoustic wave excitation. A surface acoustic wave transducer characterized by using electrode fingers with a width of λ as electrodes that contribute to wave excitation.
