PROBLEM TO BE SOLVED: To solder the input/output part of a center conductor and a connector with a notched part between them by forming this notched part in a dielectric interposed between the center conductor and an outer conductor. SOLUTION: A coaxial filter is a low pass filter and consists of an outer conductor 50 and a center conductor 51. For the purpose of preventing the center conductor 51 from bending by its own weight, oscillation, or the like, a dielectric ring 1 is put between the center conductor 51 and the outer conductor 50. The dielectric ring 1 is provided with notched parts 1 and 1b in the parts where input/output parts 54 are placed at the time of storing the input/ output parts 54 in the dielectric ring 1. Consequently, input/output parts 54 and a connector 60 can be soldered with notched parts 1a and 1b between them after input/output parts 54 are stored in the dielectric ring 1. By this constitution, the coaxial filter with the dielectric ring where the center conductor 51 and the connector 60 can be soldered is obtained. |
