Abstract
A plurality of surface acoustic wave elements, with an IDT electrodeand a pad electrodeformed on the principal surface of a piezoelectric substrate, are formed to be flip-chip mounted on a circuit boardand sealed using sealing resin. The circuit boardis diced integrally with the sealing resinapplying a rotating dicing bladefrom the bottom surface side thereof to produce a plurality of surface acoustic wave devices. The side surfaces of the surface acoustic wave devices can be formed perpendicularly with dimensional accuracy without rounding or chipping an edge portion of the sealing resin
