PROBLEM TO BE SOLVED: To facilitate forming by a forming die for a TM dual mode dielectric resonator, to realize a coupling coefficient variable structure and also to improve mass-productivity. SOLUTION: This TM dual mode dielectric resonator 2 obtained by uniting a first dielectric resonator 4 and a second dielectric resonator 5 in a cross shape is provided with grooves 6 for coupling at the front face and the rear face of the TM dual mode dielectric resonator 2. The forming die is divided into a forming die main body for forming the TM dual mode dielectric resonator 2 and an auxiliary forming die for forming the grooves for coupling, the auxiliary forming die is incorporated in the forming die main body in a freely slidable way, and the grooves 6 for coupling can be adjusted by sliding the auxiliary forming die. |
