Abstract
PURPOSE:To establish the surface acoustic wave propagation element less in propagation loss, by forming the metal thin film excellent in the crystallization between the reed screen electrodes formed on the substrate and by constituting smaller average particle diameter for the piezoelectric substance. CONSTITUTION:Between the reed screen electrodes 2 and 2' formed on the upper part of the substrate 1, the metal thin film 4 having good crystallization is formed. That is, the metal thin film 4 having good crystality is placed at the propagation path of the surface acoustic wave and the propagation loss can be reduced by decreasing the average particle diameter of the piezoelectric substance for the part.
