摘要： A surface acoustic wave device includes a package (2) having a coefficient of linear expansion; and a piezoelectric element (1) forming a surface acoustic wave element, and mounted on the package (2) by flip chip bonding. The piezoelectric element (1) has different coefficients of linear expansion in a direction of propagation of surface acoustic waves generated by an interdigital electrode of the surface acoustic wave-element and in a direction perpendicular thereto, and further has a long side (L z ) existing in a direction having a coefficient of linear expansion close to the coefficient of linear expansion of the package (2). The piezoelectric element (1) is cut out from a single crystal having X, Y, and Z crystal axes, and the X crystal axis agrees with a direction of propagation of the surface acoustic wave.
