Zusammenfassung:PURPOSE:To easily form an electrode pattern as obtaining a prescribed connection gap between surface acoustic wave resonators. CONSTITUTION:The constitution of a transverse mode connection type surface acoustic wave filter provided with a pair of surface acoustic wave resonators 12, 13 on the surface of a piezoelectric substate 11 and the connection gap G, and arranged adjacently is performed by providing insulating film 14 which covers the terminal part 12A plane on the connection gap side of the surface acoustic wave resonator 12, forming a terminal part 13A on the connection gap side of the surface acoustic wave resonator 13 on the insulating film. and obtaining the prescribed connection gap G by overlapping the terminal parts of the surface acoustic wave resonators mutually.
