Abstract

PURPOSE:To eliminate an open defect due to cracks of a reflection absorbing agent due to cut-off by constituting the coating position of the reflection absorbing agent with a gap from the chip end face orthogonal to the surface acoustic wave propagation direction so as to attain dicing not in contact with the reflection absorbing agent at the cut-off by dicing. CONSTITUTION:A comb-line input electrode 12 and an output electrode 13 are provided on a piezoelectric substrate 11 and a reflection absorbing agent 14 is applied by the screen print with a constant gap 15 from the chip end face orthogonal in the surface wave propagation direction at the end face of the input/output electrodes 12, 13 and the chip is cut off by the dicing.
