A surface acoustic wave device includes an electrode and a dielectric layer laminated on a piezoelectric substrate, in which the electrode includes a first electrode film containing Pt, Au, Ag, or Cu and a second electrode film containing Al, the normalized film thickness h\u03bb of the first electrode film is about 0. The vehicle spoiler of the present invention has first and second surfaces, which form the external shape of the vehicle spoiler and have a hollow space therebetween. The glass formulation only includes glass constituents that provide the intermediate, modifiers and any halides whose inherent absorption wavelength is longer than that of Tellurium oxide. One or more resistors are connected in series between the second common node and the transistor drain, and two or more switches are selectively operable to short circuit the resistors allowing the current sources to provide more than two current levels, thereby optimizing the image sensor current consumption for mobile devices.
