PROBLEM TO BE SOLVED: To constitute a small dielectric duplexer wherein a small TM mode dielectric resonator is used with a small loss. SOLUTION: A TM double-mode dielectric resonator 2, a TM triple-mode dielectric resonator 3 and a TM double-mode dielectric resonator 4 are aligned to permit opening faces to be turned in the same direction at a transmission side. A TM single-mode dielectric resonator 5, a TM triple-mode dielectric resonator 6 and a TM single-mode dielectric resonator 7 are arranged in the same direction in the same way. The plurality of dielectric resonators is different in the dielectric constant of a dielectric body according to a multiplex degree and unified in outer shape dimension. The opening faces are covered by a panel 8 having input/output terminals 10a and 10c, an antenna connection terminal 10b and input/output loops 9a-9d and a panel 11 having connection loops 12a-12d. Thus, the dielectric duplexer is constituted so that the outer shape dimensions are unified with a small loss.
