Abstract

圧電基板（１）上面に設けられた第１のインターディジタルトランスデューサ電極（１１０）を有する第１の弾性波共振子（１００）と、圧電基板（１）上に設けられた第２のインターディジタルトランスデューサ電極（２１０）を有する第２の弾性波共振子（２００）とを備え、第１の弾性波共振子（１００）と第２の弾性波共振子（２００）とは接続され、第１の弾性波共振子（１００）を構成する複数の第１の櫛形電極（１１２）の交差幅は、第２の弾性波共振子（２００）を構成する複数の第２の櫛形電極（２１２）の交差幅より大きい構成により、横モードスプリアスの発生周波数を分散することができ、ロスを低減することが出来る。
