摘要：
The present invention is an acoustic wave device including first and second acoustic wave resonators. A first tilt angle that is an angle formed between a direction perpendicular to a direction in which electrode fingers of the first acoustic wave resonator extend and a direction along which the electrode fingers are arranged is different from a second tilt angle that is an angle formed between a direction perpendicular to a direction in which electrode fingers of the second acoustic wave resonator extend and a direction along which the electrode fingers are arranged.
摘要（中）：
本发明是一种包括第一和第二声波谐振器的声波装置。 第一倾斜角是在与第一声波谐振器的电极指的延伸方向垂直的方向与电极指的排列方向之间形成的角度不同于第二倾斜角， 垂直于第二声波谐振器的电极指的方向延伸的方向和电极指的排列方向。
