装置。 A transducer electrode is formed on a piezoelectric substrate, sandwiched between shot-type reflectors on both sides, and one reflector is connected to one of the transducer electrodes, and the other reflector is connected to the other of the transducer electrodes. The surface wave resonator is inserted into an insulating cylinder, and the metal caps that close both ends of the cylinder are connected to the reflector parts near both left and right ends of the surface wave resonator using solder or conductive paste. A surface wave resonator featuring:
