A collector of a traveling wave tube in which a larger quantity of loss ceramic members are arranged between an outer collector enclosure and an outer surface of a collector electrode for increasing high frequency loss to prevent RF leakage from the collector lead wire. The collector includes a collector electrode 2, heat conductive columnar ceramic elements 3, an outer collector enclosure 4 for maintaining vacuum and loss ceramic members 5 arranged between the outer surface of the collector electrode 2 and the inner surface of the outer collector enclosure 4.
