    • A surface acoustic wave (SAW) filter comprising a first SAW resonator, a second SAW resonator connected in series with the first SAW resonator at a first joint, a third SAW resonator connected in series with the second SAW resonator at a second joint, a fourth SAW resonator connected in series with the third SAW resonator at a third joint, a fifth SAW resonator connected between the first joint and the ground, a sixth SAW resonator connected between the third joint and the ground, and a first capacitance component connected between the second joint and the ground and forming a capacitance. The SAW filter exhibits steep attenuation characteristics on the high band side of a pass band and thereby the pass band is widened with reduced loss.

    • Disclosed is a plasma display panel wherein a discharge space is formed by arranging a front plate and a back plate opposite to each other and hermetically sealing the peripheral portions of the front and back plates. The front plate is obtained by forming a display electrode, a dielectric layer and a protective layer on a glass substrate, while the back plate is obtained by forming an electrode, a partition wall and a phosphor layer on a substrate. The plasma display panel is characterized in that the display electrode (6) contains at least silver, that the dielectric layer (8) is composed of a first dielectric layer (81) covering the display electrode and a second dielectric layer (82) covering the first dielectric layer and containing bismuth oxide, that the first dielectric layer has a thickness of not less than 5 µm but not more than 13 µm, and that the thickness ratio of the first dielectric layer to the display electrode is more than 1 but not more than 3.
