A thin film bulk acoustic resonator comprises a substrate (12) of a silicon single crystal, a base film (13) formed on the substrate (12) and composed of a dielectric film mainly containing silicon oxide, and a piezoelectric stacked structure (14) formed on the base film (13). A vibratory section (21) composed of a part of the base film (13) and a part of the piezoelectric stacked structure (14). The piezoelectric stacked structure (14) includes a lower electrode (15), a piezoelectric film (16), and an upper electrode (17) formed in this order from below. The substrate (12) had a via hole (20) in the region corresponding to the vibratory section (21). The via hole forms a space for allowing vibration of the vibratory section (21). The piezoelectric film (16) is an aluminum nitride thin film containing 0.2 to 3.0 atom % of alkaline earth metal and/or a rare earth metal. Thus, the thin film bulk acoustic resonator has a high performance such as a large electromechanical coupling coefficient, an excellent acoustic quality factor (Q) and an excellent frequency-temperature characteristic.

A pit (52) is formed in a substrate comprising a silicon wafer (51) on a surface of which a silicon oxide thin layer (53) is formed. A sandwich structure (60) comprising a piezoelectric layer (62) and lower and upper electrodes (61, 63) joined to both surfaces of the piezoelectric layer is disposed so as to stride over the pit (52). The upper surface of the lower electrode (61) and the lower surface of the piezoelectric layer (62) joined to the upper surface of the lower electrode are treated so that the RMS variation of the height thereof is equal to 25 nm or less. The thickness of the lower electrode (61) is set to 150 nm or less. According to such a structure, there is provided a high-performance thin film bulk acoustic resonator which are excellent in electromechanical coupling coefficient and acoustic quality factor.

A vehicle lamp fixture is disclosed in which a truncated bowl-shaped reflector 6 is formed as a single unit in front of each respective LED 5. Each reflector is formed from a transparent substance and has an aperture in the front surface. Each reflector also has a reflective surface 6b that totally reflects light from the LED 5 and a light conductive member 6c that conducts at least a portion of light reflected by the reflective surface toward the front of the light fixture. A transparent front lens can thereby be used that does not include light-distributing facets.

A vehicle lamp is disclosed that includes plural light sources located on a printed wiring board. A first reflection structure reflects light from the light sources to a light emitting surface, and a second reflection structure reflects light reflected from the first reflection structure in an illuminating direction of the vehicle lamp. The construction of the lamp's first and the second reflection structures permits the light emitting surface of the vehicle lamp to shine uniformly. Accordingly, the number of the light sources required is minimized.
