Abstract

PURPOSE:To obtain a uniform characteristics as well as to facilitate an easy coating work by coating the surface wave absorbing agent through the slit provided on the screen. CONSTITUTION:A pair of slits 9 and 10 are provided to stainless steel mask 8. Mask 8 is applied on the element to which comb-lined electrode 12 and 13 are provided on piezoelectric substrate 11, and then the surface wave absorbing agent such as the silicon rubber or the like is coated through slit 9 and 10. In case the thermoplastic resin powder is used for the surface wave absorbing agent, screen 8 is made float a little above the surface of substrate 11. Then the resin powder is applied to the fixed areas through the slit on screen 8, and then the absorbing agent is fixed to substrate 11 through heating.
