PROBLEM TO BE SOLVED: To simplify the process of manufacturing the collector structure of a multiple-collector-type traveling-wave tube and to miniaturize the structure by simplifying a feeding structure for electrodes. SOLUTION: This multiple-collector-type traveling-wave tube includes a cylindrical ceramic insulating member 127c coaxially joined with the inner peripheral wall of a heat radiator part 129 forming the shell of a collector part, a metallized layer electrically insulated from the surface of the inner peripheral wall and consisting of a first metallized layer 135a and a second metallized layer 135b, a front-stage first collector electrode 126 placed upstream of an electron beam and having a first cylinder part with the first metallized layer joined thereto, a rear-stage second collector electrode 128 placed downstream of the electron beam inside the metallized layer and having a second cylinder part with the second metallized layer joined thereto, and a first lead wire 131a and a second lead wire 131b for supplying electric potential respectively to the first collector electrode 126 and the second collector electrode 128.
