Summary:PURPOSE: A structure of a duplexer and a method for manufacturing the same are provided to improve an attenuation characteristic and reduce a size of a duplexer. CONSTITUTION: A structure of a duplexer and a method for manufacturing the same comprise a dielectric block(50), a multitude of resonator(R1-R7), an electrode pattern(51a), a transmission/reception portion, a channel(53a,53b,53c), and a slit. The dielectric block comprises a first step and a second step. The resonators are formed on an opening face adjacent to the first step face of the dielectric block. The electrode pattern combines the first step face with resonators. The transmission/reception portion transmits and receives a signal. The channel is formed at a location adjacent to a specific resonator. The slit comprises an electrode for connecting electrically the electrode pattern with an inner conductor of the resonator.
