The patent describes an acoustic surface wave delay line having a lithium niobate substrate member the surface wave propagation plane of which is parallel to the lithium niobate crystalline X axis and intersects the crystalline Z and -Y axes. Optimum results are obtained when the intersecting angle of the propagation plane and the Z axis is in the vicinity of 48.5 degrees.
