A surface acoustic wave component includes a piezoelectric substrate and
an electrode structure that includes multiple layers and that is on the
piezoelectric substrate. A dielectric layer is above the electrode
structure. The dielectric layer has an acoustic impedance Z.sub.a,d. The
multiple layers include a first layer system that includes at least one
first layer made of a first material, which has an acoustic impedance
that is less than 2Z.sub.a,d. The second layer system includes at least
one second layer made of a second material, which has an acoustic
impedance that exceeds 2Z.sub.a,d. The second layer system has a height
that is between 15% and 85% of a total height of the multiple layers.
