This invention provides a surface acoustic wave (SAW) filter, comprising a piezoelectric layer and interdigitated electrodes. The interdigitated electrodes are disposed on the piezoelectric layer and include at least a first metal layer and a second metal layer stacked together. The first metal layer is made of platinum or an alloy with platinum as the main component, and the second metal layer is made of aluminum or an alloy with aluminum as the main component. By setting the material of the second metal layer to aluminum or an alloy with aluminum as the main component, the uniformity of metal coverage of the electrode structure can be effectively improved, avoiding excessive local resistance or structural defects caused by poor coverage. Setting the material of the first metal layer to platinum or an alloy with platinum as the main component provides reliable support for the second metal layer, reducing the risk of deformation or corrosion of the aluminum layer in subsequent processes. By using a stacked structure of two complementary materials for the interdigitated electrodes, both structural miniaturization and improved overall electrical performance and structural reliability of the interdigitated electrodes are achieved.
