Abstract

In an electronic component having reflecting structures on a substrate body and functioning with reflected acoustic waves traveling thereon, at least one longitudinal lateral edge of the substrate body is aligned at an angle .delta. deviation from a direction parallel relative to an acoustic wave emitted by an input transducer. The dimension of the angle .delta. depends on the arrangement of an output transducer. This construction minimizes the appearance of spurious signals.
