Abstract

PURPOSE:To make it possible to form a ceramic filter accurately at high yield by providing grating-shaped concave grooves in a piezoelectric ceramic substrate, by providing through holes at intersections between longitudinal grooves and lateral grooves, and by forming electrodes in respective grating sections. CONSTITUTION:Concave grooves S1 and S2 are formed in a grating shape on the surface of piezoelectric ceramic substrate 13 and at intersections between longitudinal concave grooves S1 and lateral concave grooves S2, through holes 14 are made. Next, an electrode is printed in area Q1 surrounded with longitudinal groove S1 and lateral groove S2. Then, piezoelectric ceramic substrate 13 is folded along longitudinal grooves S1 and further folded along lateral grooves S2.
