Abstract
A surface acoustic wave elementincludes an IDT electrodehaving an electrode fingeron a piezoelectric substrate. The electrode fingeris formed by laminating an intermediate layerand an electrode layerhaving a higher coefficient of thermal expansion than that of the intermediate layer. The electrode fingerhas a cross section of a trapezoidal shape that widens nearer to the piezoelectric substrate. An angle αformed with a side surface of the intermediate layeris formed larger than an angle βformed with a side surface of the electrode layer
